CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2018-179444 filed Sep. 25, 2018.

BACKGROUND
(i) Technical Field

The present disclosure relates to a non-transitory computer readable medium and an information processing apparatus.

(ii) Related Art

There is known an information processing apparatus that converts image data to be printed into print data of all of a plurality of data types preset before a printing device that executes a print process is selected upon receiving a print instruction for the image data, acquires information on data types printable by a printing device from the printing device when the printing device is selected to execute the print process by a user, selects print data printable by the printing device which is selected to execute the print process from among the plurality of data types of converted print data on the basis of the acquired information on the printable data types, and transmits the selected print data to the printing device through a near-field wireless communication section or the like (see Japanese Unexamined Patent Application Publication No. 2018-49435).

SUMMARY

When printing data, it is necessary to generate a page description language (PDL) file for the data. The type of the PDL file may differ depending on the printing device which prints the data. Thus, if the PDL file is generated after the printing device to print the data is selected, it takes time to start printing of the data. In the case where a plurality of types of PDL files are generated for the entire data before the printing device to print the data is selected, a PDL file of a type supported by the printing device is selected when the printing device is selected, and the selected PDL file is transmitted to the printing device, in contrast, the plurality of types of PDL files for the entire data squeezes the storage region while reducing the time before the start of printing of the data.

Aspects of non-limiting embodiments of the present disclosure relate to reducing the time before an unspecified printing device starts printing while saving a storage region compared to a case where a plurality of types of PDL files are generated for the entire data.

Aspects of certain non-limiting embodiments of the present disclosure overcome the above disadvantages and/or other disadvantages not described above. However, aspects of the non-limiting embodiments are not required to overcome the disadvantages described above, and aspects of the non-limiting embodiments of the present disclosure may not overcome any of the disadvantages described above.

According to an aspect of the present disclosure, there is provided a non-transitory computer readable medium storing a program causing a computer to execute a process including: generating a plurality of page description language (PDL) files written in a plurality of types of PDLs for one portion of data; and performing control such that the plurality of generated PDL files and a different portion of the data other than the one portion are stored in an internal or external storage device in association with each other.

Then, the image processing apparatus 30 stands by until all the corresponding PDL file for the first page is received from the portable terminal 10. The image processing apparatus 30 starts printing on the basis of the corresponding PDL file for the first page when all the corresponding PDL file for the first page is received (step S454).

After that, the image processing apparatus 30 receives the corresponding PDL file for the second and subsequent pages (step S455). Then, the image processing apparatus 30 starts printing on the basis of the corresponding PDL file for the second and subsequent pages when all the corresponding PDL file for the second and subsequent pages is received (step S456).

In the above description, the portable terminal 10 downloads the corresponding PDL file for the first page, and transmits such a file to the image processing apparatus 30. However, the present disclosure is not limited thereto. The corresponding PDL file for the first page may be directly downloaded from the server 50 to the image processing apparatus 30. In the former, the print instruction section 27 transmits the corresponding PDL file for the first page to the image processing apparatus 30. In this case, the function of the print instruction section 27 is an example of a first output function to output the first PDL file to the printing device as the print instruction. In the latter, the print instruction section 27 instructs the image processing apparatus 30 or the server 50 such that the corresponding PDL file for the first page is directly transmitted from the server 50 to the image processing apparatus 30. In this case, the function of the print instruction section 27 is an example of a first output function to output an instruction that causes the first PDL file, among the plurality of PDL files which are stored in an external storage device, to be transmitted to the printing device not by way of a computer as the print instruction.

Although not mentioned above, the server 50 may be provided with a rendering function based on the PDL file for the first page. Consequently, the image processing apparatus 30 is provided with a print instruction for the first page with changed print setting even in the case where print setting is changed on the portable terminal 10.

[Modifications]

(First Modification)

In the first and second exemplary embodiments, the PDL file generation section 23 generates one set of a plurality of PDL files that matches one print setting beforehand. In order to support a change in print setting, however, the PDL file generation section 23 may generate a plurality of sets of a plurality of PDL files that match a plurality of print settings beforehand. For example, three sets of a plurality of PDL files that match a case where only double-sided print is set, a case where only print in which two pages are collectively printed on one medium is set, and a case where both double-sided print and print in which two pages are collectively printed on one medium are set may be generated in addition to one set of a plurality of PDL files for a case where neither double-sided print nor print in which two pages are collectively printed on one medium is set according to the first and second exemplary embodiments. In this case, the function of the PDL file generation section 23 is an example of a first generation function to generate a plurality of PDL files for each of a plurality of print settings.

In this first modification, a plurality of patterns that match the plurality of print settings may be prepared also for a portion of the document that is not converted into a PDL beforehand. Alternatively, only one pattern that covers all the patterns, among a plurality of patterns that match a plurality of print settings, may be prepared, and a necessary portion may be cut out from the one pattern to be used when the print setting is determined. In the example discussed above, it is conceivable to prepare four patterns, that is, the second and subsequent pages for a case where neither double-sided print nor print in which two pages are collectively printed on one medium is set, the third and subsequent pages for a case where only double-sided print is set, the fourth and subsequent pages for a case where only print in which two pages are collectively printed on one medium is set, and the fifth and subsequent pages for a case where both double-sided print and print in which two pages are collectively printed on one medium are set. However, only the second and subsequent pages, which cover all the patterns, may be prepared.

(Second Modification)

In the first and second exemplary embodiments, the PDL file generation section 23 converts the first page of a document into a PDL beforehand. However, the page to be converted may be changed in accordance with the print setting. For example, in the case where double-sided print is set, a plurality of PDL files may be generated beforehand for up to the second page of a document. In general, the PDL file generation section 23 preferably generates a plurality of PDL files beforehand for pages to be printed on a first medium in accordance with the print setting. In this case, the function of the PDL file generation section 23 is an example of a first generation function to generate a plurality of PDL files for one portion which is to be printed on a first medium in the case where each print setting is applied.

(Third Modification)

In the first modification, the PDL file generation section 23 generates a plurality of sets of a plurality of PDL files that match a plurality of print settings beforehand. However, print setting may be determined before a plurality of PDL files are generated beforehand. An example of a method of determining the print setting is considered to be a method including saving print setting as a separate file when the user saves a document and determining the print setting on the basis of the separate file. Determining the print setting by this method is an example of specifying the print setting on the basis of information saved in association with data. Another example of the method is considered to be a method including receiving a print setting input from the outside. Consequently, a PDL file that matches a specific print setting is generated when saving a document or when reading a document.

(Fourth Modification)

In the case where print setting may not be determined before a plurality of PDL files are generated beforehand, the PDL file generation section 23 may generate a plurality of PDL files that match default print setting. Examples of the case where print setting may not be determined include a case where print setting is not saved as a separate file and a case where print setting is not input from the outside. In this case, the function of the PDL file generation section 23 is an example of a first generation function to generate a plurality of PDL files for a predetermined print setting in the case where information for specifying the print setting is not saved in association with data.

(Fifth Modification)

In the second to fourth modifications, the PDL file generation section 23 may be considered as specifying one or more print settings before print setting is input in a print request for the image processing apparatus 30, and generating a plurality of PDL files for each of the one or more print settings. In this case, the function of the PDL file generation section 23 is an example of a first generation function to generate a plurality of PDL files for each of one or more print settings specified before print setting is input in a print request for the printing device to print data.

(Sixth Modification)

In the first and second exemplary embodiments, the PDL file generation section 23 generates a plurality of PDL files beforehand for the first page of a document. However, the PDL file generation section 23 may generate a plurality of PDL files beforehand for a portion including the first and subsequent pages of a document. For example, the PDL file generation section 23 may generate a plurality of PDL files for a portion that matches the size of a document, such as generating a plurality of PDL files for the first ten pages in the case where the document contains 100 pages. In this case, the function of the PDL file generation section 23 is an example of a first generation function to generate a plurality of PDL files for one portion that matches the size of the data.

The portion that matches the size of a document may be a portion in a fixed proportion of the entire document such as 1:10, for example. In this case, a portion of a document is an example of a portion with a size that is in a predetermined proportion to the size of the data.

Alternatively, the portion that matches the size of a document may be a portion of the entire document in a variable proportion, for example. The proportion may be varied in accordance with a certain rule. In this case, a portion of a document is an example of a portion with a size that is in a proportion, which is determined in accordance with a predetermined rule, to the size of the data. A method of determining a proportion to the entire document is considered to be a method including determining the proportion on the basis of the speed of printing based on a corresponding PDL file for that portion by the image processing apparatus 30, and a method including determining the proportion on the basis of the speed of generating a corresponding PDL file for a different portion other than that portion. The former is an example of a case where the predetermined rule uses the print speed of the printing device which prints the data, and the latter is an example of a case where the predetermined rule uses the generation speed of generation of a PDL file for the different portion.

(Seventh Modification)

Although not mentioned in relation to the first and second exemplary embodiments, the portable terminal 10 may delete at least part of a plurality of PDL files for the first page of a document in the case where a certain condition is met after such a plurality of PDL files are generated beforehand. In this case, the deleting function is an example of a deleting function to delete at least part of a plurality of PDL files in the case where a predetermined condition is met.

An example of a condition for deleting at least part of a plurality of PDL files is considered to be that the image processing apparatus 30 prints a corresponding PDL file designated from among a plurality of PDL files. In this event, the other PDL files, which are not designated, are not necessary, and are therefore preferably deleted. This is an example of a case where the predetermined condition is that the data have been printed by the printing device.

Another condition for deleting at least part of a plurality of PDL files is considered to be that the image processing apparatus 30 does not use the plurality of PDL files for printing for a predetermined period since such PDL files are saved. In this event, all the plurality of PDL files for a portion of a document are preferably deleted. This is an example of a case where the predetermined condition is that a predetermined time has elapsed since the plurality of PDL files are saved.
