Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a printing apparatus having a plurality of print modes and a plurality of paper feeders and relates to a print control apparatus and a method which is used for those apparatuses.
2. Related Background Art
In recent years, print documents have been formed by various print media in accordance with various applications. For example, not only a print document is printed to a standard paper in order to form a document or the like but also a print document is printed by various printing apparatuses to an OHP sheet for an OHP which is used for reading of researches or the like, a thick paper such as a postcard, or the like. Therefore, even in a printing apparatus for outputting a document formed by a word processor, a computer system, or the like, a function to print the document by a plurality of media such as OHP sheet, thick paper, and the like other than the standard paper is provided.
As for those print media, since features such as thickness, concave and convex states of the surface, hygroscopic property, and the like differ, a printing process is performed in accordance with each print medium. For example, since the thick paper such as a postcard or the like is thicker than the standard paper, a feed roller and a conveying roller adapted to the standard paper are improper for the thick paper. Since the ink cannot be uniformly transferred depending on the concave and convex states of the paper surface, a character quality deteriorates. Further, in the case where the hygroscopic property of the paper is low, there is a fear such that the printed characters blot.
In the printing apparatus, therefore, by presetting the print mode corresponding to a desired print medium, the proper printing processes corresponding to various print media can be performed.
In the case where the printing can be performed by a plurality of kinds of print media, if only one paper feeder is provided, it is troublesome to exchange the print media. To prevent such a problem, a plurality of paper feeders are usually provided. To print to a desired print medium, therefore, it is necessary not only to designate the print mode but also to select the paper feeder in which the desired print media are enclosed.
However, there is a problem such that a desired print quality cannot be obtained in the case where the print mode and the print medium are not matched as in a case where the operator erroneously designates the print mode, a case where even if the operator correctly designated the print mode, the print media corresponding to the designated print mode are not enclosed in the selected paper feeder, or the like.
SUMMARY OF THE INVENTION
It is, therefore, an object of the invention to provide a printing apparatus having a plurality of print modes and a plurality of paper feeders, wherein it is prevented that the printing is performed by different print media, and the printing can be certainly executed in a desired print made or by a desired print medium.
To solve the above problems, according to the invention, there is provided a printing apparatus having a plurality of print modes and a plurality of paper feeders and in which predetermined print media are enclosed in each paper feeder, comprising: means for designating a print mode; means for selecting the paper feeder; and means for detecting whether the designated print mode and the print mode which is available in the selected paper feeder coincide or not.
The invention also uses a construction having means for detecting whether the print medium corresponding to the designated print mode and the print media enclosed in the selected paper feeder coincide or not.
According to this construction, since whether the designated print mode and the print mode which is available for the selected paper feeder coincide or not can be detected, the print data can be certainly outputted in the desired print mode. Since whether the print medium corresponding to the designated print mode and the print media enclosed in the selected paper feeder coincide or not can be detected, it is possible to prevent that the print data is outputted by the different print medium.
According to the invention, since whether the designated print mode and the print mode which is available for the selected paper feeder coincide or not can be detected, the print data can be certainly outputted in the desired print mode. Since whether the print medium corresponding to the designated print mode and the print media enclosed in the selected paper feeder coincide or not is detected, it is possible to prevent that the print data is outputted by the different print medium. In this case, by tentatively setting the print media enclosed in the paper feeder, even for a printing apparatus without a function for detecting the print media, it is possible to prevent that the print data is printed by a different print medium.
The above and other objects and features of the present invention will become apparent from the following detailed description and the appended claims with reference to the accompanying drawings.

1000
and analyzing the character information or the like which is supplied from the host computer. The control unit
1001
mainly converts the character information to a video signal of a corresponding character pattern and outputs to a laser driver
1002
. The laser driver
1002
is a circuit for driving a semiconductor laser
1003
and on/off switches a laser beam
1004
which is emitted from the semiconductor laser

in accordance with an inputted video signal.
The laser beam
1004
is swung to the right and left by a rotary polygon mirror
1005
and scans on an electrostatic drum
1006
, so that an electrostatic latent image of the character pattern is formed on the electrostatic drum
1006
. This latent image is developed by a developing unit
1007
arranged around the electrostatic drum
1006
and, after that, is transferred onto a print medium. The print medium is, for example, a cut sheet. The print medium of the cut sheet is enclosed in a paper cassette (paper feeder)
1008
attached to the LBP
1000
, is picked up into the apparatus by a feed roller
1009
and conveying rollers
1010
and
1011
, and is fed to the electrostatic drum
1006
. The image transferred to the print medium is subsequently fixed by a fixing unit
1015
. In this case, a fixing temperature is adjusted in accordance with the print mode designated from the host computer.
Reference numeral
1013
denotes a paper feed tray for taking the print medium into the apparatus by the conveying rollers
1010
and
1011
. The kind of print medium which is fed from the paper cassette
1008
, a paper cassette
1016
, or the paper feed tray
1013
(hereinafter, they are generally referred to as a “paper feeder”) is detected by a print medium detecting sensor
1014
provided in the paper feeding unit. Reference numeral
1016
denotes the cassette at the second stage which can enclose print media of the kind that is the same as or different from the kind of print media enclosed in the cassette at the first stage.
FIG. 2
is a diagram showing the relation between block constructional diagram of the LBP in the embodiment and a data generating source. Component elements
202
to
206
shown in the diagram are included in the foregoing printer control unit
1001
and a construction of a printer section is as described in FIG.
1
.
Various data from the host computer
201
serving as a data source is supplied to the CPU
203
for controlling the controller through the input/output (I/O) buffer
202
. A program and font patterns are stored in an ROM
204
. Various processing data is stored into an RAM
205
serving as a work area. Developed images are stored into a page buffer
206
. The developed images are printed onto the print medium through a printer engine
207
.
FIG. 3
shows a command which is designated from the host
201
serving as a data source. This command is constructed by: an ESC code
301
showing that this command is a control command; a code
302
showing that this command is a designating command of the print mode; and a code
303
showing the print mode.
FIG. 4
shows another command which is designated from the host
201
. This command is constructed by: an ESC code
401
showing that the command is a control command; a code
402
showing that the command is a selecting command of a paper feeder; and a code
403
showing the contents of the paper feeder selection. As a code
403
, in addition to the code corresponding to the paper feeder to be selected, a code to designate an automatic mode can be also used.
FIG. 5
is a diagram showing an example of the relation between the paper feeder and the print mode that can be designated. A left column
501
denotes a kind of paper feeder and a right column
502
shows a print mode which can be set to the paper feeder in the left column. For example, it is shown that a print mode “thick/OHP”
504
can be set to a multipurpose tray (hereinafter, abbreviated to an MP)
503
(corresponding to the paper feed tray
1013
in FIG.
1
), a print mode “standard/thick”
506
can be set to an upper cassette
505
(corresponding to the paper feeder
1008
in FIG.
1
), and a print mode “standard/thick”
508
can be set to an lower cassette
507
(corresponding to the paper feeder
1016
in FIG.
1
), respectively.
A print processing procedure in the first embodiment of the invention will now be described hereinbelow with reference to a flowchart shown in FIG.
8
.
In step
801
, when a power source is turned on, the present program is started. In step
802
, whether data has been received from the host computer
201
to a port or not is discriminated. When there is no data, this discrimination is repeated.
When the data is received, a check is made in step
803
to see if the received data is a control command. When it is not the control command, since this means that the received data is print data, the received data is analyzed and converted into an internal code in step
804
. The internal code is written into the page buffer
206
in step
805
.
When it is determined in step
803
that the received data is the control command, whether the control command is a designating command of the print mode or not is discriminated in step
806
by referring to the next code (code
302
in FIG.
3
). When it is decided in step
806
that the control command is the designating command of the print mode, the print mode of the code
303
(
FIG. 3
) is set in step
807
. When it is determined in step
806
that the control command is not the designating commend of the print mode, a check is made in step
808
to see if it is a selecting command of the paper feeder. When it is decided in step
808
that the control command is not the selecting command of the paper feeder, the control command is analyzed in step
809
and is written into the page buffer
206
as necessary. As illustrated in
FIG. 8
, steps
806
and
807
are performed independently.
On the other hand, when it is determined in step
808
that the control command is the selecting command of the paper feeder, whether the foregoing automatic mode has been designated or not is confirmed in step
810
by referring to the code
403
in FIG.
4
. When the selecting command of the paper feeder designates the automatic mode, a check is made in step
811
to see if the print medium exists in the current paper feeder. If there is no print medium, in step
807
, the paper feeder in which the designated print mode is available is moved to the paper feeder in which the print media corresponding to the print mode exist as a selection target. The discrimination about the possibility can be made with reference to the relation between the columns
501
and
502
in FIG.
5
. For example, in the case where the print mode relates to the standard paper, only the upper and lower paper feeders become the selection targets. On the contrary, when it is decided in step
810
that the selecting command is not the automatic mode, the designated paper feeder is selected in step
812
. The selecting operation of the paper feeder in step
811
will now be described with reference to FIG.
10
.
The paper feeder when the automatic mode is selected is selected as follows.
First in step A
02
, the designated print mode and medium are determined. When the print mode is not designated by the control command and step
807
in
FIG. 8
is not executed, the print mode and medium are determined by those defined as a default. In step A
03
, the paper feeder is tentatively selected. In step A
03
, the paper feeder is sequentially selected until the paper feeder to be selected is determined. Ordinarily, the tray is first selected and, subsequently, the cassette is sequentially selected. In step A
04
, a check is made to see if the print mode designated by the selected paper feeder can be designated. If YES, in step A
05
, the presence or absence of the medium is discriminated and whether the present medium coincides with the designated medium or not is further checked. When the designated medium exists on the selected paper feeder, it is determined as a paper feeder to start the paper feed and a process A
06
is finished.
In the case where the designated print mode is impossible in the selected paper feeder (in this example, when the OHP is designated in the cassette) or the case where no medium exists or, even if the medium exists, it is not the designated medium, a check is made in step A
07
to see if all of the paper feeders have been confirmed. If NO, the processing routine is returned to step A
03
and the next paper feeder is selected. In the last case, an error is notified to the operator and the process is finished (step A
08
).
In the foregoing case, although the size of medium is not described, preferably in step A
05
, when a designating command of a size of medium is received from the host, the coincidence is discriminated with respect to the above items including the size of medium.
When the print mode is designated and the paper feed is selected as mentioned above, a check is made in step
813
to see if there is a page to be outputted. If NO, the processing routine is returned to step
802
and data is inputted. When there is the page to be outputted, a check is made in step
814
to see if the automatic mode has been set. When the automatic mode is not set, a check is made in step
815
to see if the print medium has been enclosed in the current paper feeder. If the print medium is not enclosed, an error is notified in step
816
. This error can be cancelled by supplementing the print media into the current paper feeder or by again selecting the paper feeder by the operation panel
1012
. When the automatic selecting mode is confirmed in step
814
, the paper feeder is automatically selected in consideration of the print medium and the print mode in a manner similar to the process in step
811
(step
817
).
Subsequently, in step
818
, by checking the tables
501
and
502
in
FIG. 5
, a check is made to see if the print mode which is available in the selected paper feeder and the print mode designated in step
807
coincide, namely, whether the printing by the print mode designated in the selected paper feeder is possible or not is discriminated. For example, in the case where the OHP is designated as a print mode in spite of a fact that the cassette (1) has been selected as a paper feeder, an error is notified in step
819
. In this case, if the automatic mode is selected in step
810
, since the paper feeder in which the print mode is available has been selected, no error is notified. When the error is notified in step
819
, by changing the paper feeder, the error can be cancelled.
Subsequently, a check is made in step
820
to see if the print medium corresponding to the designated print mode and the print media actually enclosed coincide. In this case, the kind of print medium can be detected by the detecting sensor
1014
provided in the LBP. When the print media do not coincide, an error is notified in step
821
. For example, in the case where the enclosed print medium is the OHP in spite of a fact that the print mode is designated as a thick paper, an error is notified. In this case, the operator can cancel the error by making the print medium coincide with the correct medium or by performing an error skip. In case of the error skip, in step
822
, the designation according to the enclosed print media is performed for the printer engine. When the print medium corresponding to the print mode coincides with the print media which were actually enclosed, the print data is outputted in the print mode designated in step
807
(step
822
).
Subsequently, a check is made in step
823
to see if there is still any other page to be outputted. When there is the page to be outputted, the processing routine is returned to step
813
and the processes mentioned above are repeated. When there is not the page to be outputted, it is assumed that all of the print documents have been printed, and the printing process is finished (step
824
).
[Second Embodiment]
Although the embodiment has been described on the assumption that the detecting sensor
1014
to detect the print medium is provided, an example in the case where there is no detecting sensor will now be described. The second embodiment is similar to the first embodiment except that there is no detecting sensor
1014
, an overlapped description is omitted, and different points will now be mainly explained.
FIG. 6
shows another command which is designated from the host
201
serving as a data source. This command is constructed by: an ESC code
601
showing that this command is the control command; a code
602
showing that this command is a setting command of the tentative print medium of the paper feeder; a code
603
showing the kind of tentative print medium; and a code
604
showing the kind of paper feeder.
FIG. 7
is a diagram showing an example of the relation between the paper feeder and the tentative print medium. The kind of paper feeder is shown in a left column
701
. The kind of print medium which is tentatively set to each paper feeder is shown in a right column
702
. For example, a print medium “thick”
704
is tentatively set to an MP
703
. A print medium “thick”
706
is tentatively set to an upper cassette
705
. A print medium “standard”
708
is tentatively set to a lower cassette
707
.
The operation of the embodiment will now be described with reference to a flowchart shown in FIG.
9
.
First in step
901
, when the power source is turned on, the present program is started. In step
902
, a check is made to see if data has been received from the host computer
201
to the port. When there is no data, this checking process is repeated.
When the data is received, a check is made in step
903
to see if the received data indicates the control command. When it is not the control command, since it is the print data, the received data is analyzed and is converted into an internal code in step
904
. The internal code is written into the page buffer
206
in step
905
.
When it is determined in step
903
that the received data is the control command, a check is made in step
906
to see if the control command is the designating command of the print mode by referring to the next code (code
302
in FIG.
3
). When it is decided in step
906
that the control command is the designating command of the print mode, the print mode of the code
303
(
FIG. 3
) is set in step
907
. When it is decided in step
906
that the control command is not the designating command of the print mode, a check is made in step
908
to see if the control command is the selecting command of the paper feeder.
When it is decided in step
908
that the control command is not the selecting command of the paper feeder, a check is made in step
909
to see if the control command is the setting command of the medium. If NO, the control command is analyzed in step
910
and is written into the page buffer
206
if necessary.
When it is determined in step
909
that the control command is the setting command of the medium, the kind of medium shown by the code
603
of the control command shown in FIG.
6
and the paper feeder shown by the code
604
are set into the table in
FIG. 7
in step
911
. In this example, “thick” is tentatively set to the paper feeder MP, “thick” is tentatively set to the upper cassette, and “standard” is tentatively set to the lower cassette. By this setting, even in the printing apparatus without the print medium detecting function, when the paper feeder is decided, the print medium enclosed therein can be tentatively set.
On the other hand, when it is determined in step
908
that the control command is the selecting command of the paper feeder, whether the mode is the automatic mode or not is confirmed in step
912
by referring to the code
403
in FIG.
4
. When the selecting mode of the paper feeder is the automatic mode, a check is made in step
914
to see if there is the print medium in the current paper feeder. If there is no medium, the paper feeder in which the print mode designated in step
907
is possible is set to the selection target and is shifted to the paper feeder in which the print media corresponding to the print mode exist. The discrimination about whether the designated print mode is possible or not can be made by referring to the relation of
501
and
502
in FIG.
5
. For example, when the print mode relates to “standard”, only the upper and lower cassettes become the selection targets. On the other hand, when it is determined in step
912
that the selecting mode is not the automatic mode, the paper feeder is shifted to the paper feeder designated in step
913
.
As mentioned above, when the print mode is designated and the paper feeder is selected, the presence or absence of the page to be outputted is discriminated in step
915
. When there is no page to be outputted, the processing routine is returned to step
902
and the data is inputted. When there is the page to be outputted, a check is made in step
916
to see if the selecting mode is the automatic mode. When it is not the automatic mode, a check is made in step
917
to see if the print media have been stored in the current paper feeder. When the print media do not exist, an error is notified in step
919
. This error can be cancelled by supplementing print media to the current paper feeder or by again selecting the paper feeder by the operation panel
1012
. When it is confirmed in step
916
that the selecting mode is the automatic mode, the paper feeder is automatically selected in consideration of the print medium and the print mode (step
918
) in a manner similar to the process in step
914
.
The selecting operations of the paper feeder in steps
914
and
918
are similar to the processes shown in FIG.
10
. Preferably, the discrimination in step A
05
is performed with reference to the table in
FIG. 7
with regard to the paper feeder in which the print medium has been tentatively set and is executed with reference to the table in
FIG. 5
with respect to the paper feeder in which the print medium is not set.
Subsequently in step
920
, by checking the tables of
501
and
502
in
FIG. 5
, a check is made to see if the print mode which is possible in the selected paper feeder and the print mode designated in step
907
coincide, namely, whether the printing in the designated print mode can be performed in the selected paper feeder or not is discriminated. For example, when the OHP is designated as a print mode in spite of a fact that the upper cassette has been selected as a paper feeder, an error is notified in step
921
. In this case, when the automatic mode is selected in step
912
, since the paper feeder in which the print mode is available has been selected, no error is notified. When the error is notified in step
921
, the error can be cancelled by changing the paper feeder.
A check is made in step
922
to see if the print medium corresponding to the designated print mode and the actual print medium coincide. In this case, the kind of print medium is detected with reference to the table shown in FIG.
7
. When the print media do not coincide, an error is notified in step
923
. For example, when the MP
703
is selected in
FIG. 7
, the kind of print medium has been tentatively set to “thick”
704
. Therefore, when the OHP is designated as a print mode in step
907
, an error is notified. In this case, the operator can cancel the error by making the print medium coincide with the correct medium and by changing the tentatively set print medium by the operation panel. In case of an error skip, in step
924
, the designation according to the tentatively set print medium is performed for the printer engine. On the other hand, when the print medium corresponding to the print mode and the tentatively set print medium coincide, the print data is outputted in the print mode designated in step
907
(step
924
).
Subsequently, a check is made in step
925
to see if there is still another page to be outputted. When there is the page to be outputted, the processing routine is returned to step
915
and the processes mentioned above are repeated. When there is no page to be outputted, it is regarded that all of the print documents have been printed, and the printing process is finished (step
926
).
