Claims
- 1. A printer capable of printing on at least two types of recording paper, said printer comprising:
- printing means for printing on said at least two types of recording paper with a single print head;
- recording paper transfer means for independently transferring said at least two types of recording paper to said printing means;
- a plurality of return amount memory means for respectively storing return amount values corresponding to said at least two types of recording paper, wherein said return amount values represent an amount by which said recording paper must be transferred between printing operations on successive lines;
- an interface for receiving a control command code for controlling a printing operation from a host computer;
- control command analyzing means for interpreting said control command code received from said host computer;
- recording paper selecting means for selecting one of said at least two types of recording paper based upon said control command code; and
- control means for controlling said plurality of return amount memory means for storing said return amount values and for retrieving a return amount value from one of said plurality of return amount memory means corresponding to a selected one of said at least two types of recording paper.
- 2. A method for controlling a printing operation of a printer which includes printing means for printing on at least two types of recording paper with a single print head, recording paper transfer means for independently transferring said at least two types of recording paper to said printing means, a plurality of return amount memory means for respectively storing return amount values corresponding to said at least two types of recording paper, an interface for receiving a control command code for controlling a printing operation from a host computer, control command analyzing means for interpreting said control command code received from said host computer, recording paper selecting means for selecting one of said at least two types of recording paper based upon said control command code, and control means for controlling said plurality of return amount memory means and for retrieving a return amount value from one of said plurality of return amount memory means corresponding to a selected one of said at least two types of recording paper, said method comprising the steps of:
- receiving a control command code from said host computer;
- interpreting said control command code received from said host computer;
- selecting one of said at least two types of recording paper to be supplied to said printing means for said printing operation based upon said control command code; and
- storing a return amount value based upon a selected recording paper for controlling a return operation of said printing means between printing on successive lines of said selected recording paper.
- 3. The method according to claim 2, wherein said printing operation for said selected recording paper comprises the steps of:
- transferring said selected recording paper to a printing position by said recording paper transfer means;
- driving said print head to perform said printing operation;
- executing said return operation based upon said return amount value corresponding to said selected recording paper; and
- repeating said transferring of said selected paper, said driving of said print head and said return operation until said printing operation is completed.
- 4. A printer capable of printing on at least two types of recording paper, said printer comprising:
- a print head;
- a recording paper transfer mechanism configured to transport, independently, at least the two types of recording paper to a position facing said print head;
- a plurality of return amount memories for storing respective return amount values corresponding to the at least two types of recording paper, wherein the return amount values represent a paper feed amount between successive lines of print; and
- a processor controlling said recording paper transfer mechanism and said return amount memories in accordance with control command codes received from a host computer, such that the received control command codes (a) control said return amount memories to output a return amount value corresponding to a selected one of the at least two types of recording paper and (b) control said recording paper transfer mechanism to transport the selected type of recording paper by a return amount corresponding to the return amount value output by said return amount memories.
- 5. A printer capable of printing on at least two types of recording paper, said printer comprising:
- printing means for printing on said at least two types of recording paper with a single print head;
- recording paper transfer means for independently transferring said at least two types of recording paper to said printing means;
- a plurality of return amount memory means for respectively storing return amount values corresponding to said at least two types of recording paper, wherein said return amount values represent an amount by which said recording paper must be transferred between printing operations on successive lines;
- an interface for receiving a control command code for controlling a printing operation from a host computer;
- control command analyzing means for interpreting said control command code received from said host computer;
- first recording paper selecting means for selecting one of said at least two types of recording paper for which the return amount value is to be set based upon said control command code;
- second recording paper selecting means for selecting at least one of said at least two types of recording paper to be transferred by said recording paper transfer means based upon said control command code; and
- control means for controlling said plurality of return amount memory means for storing said return amount values corresponding to the recording paper selected by said first recording paper selecting means and for retrieving at least one of said return amount values corresponding to the recording paper selected by said second recording paper selecting means.
- 6. A method for controlling a printing operation of a printer which includes printing means for printing on at least two types of recording paper with a single print head, recording paper transfer means for independently transferring said at least two types of recording paper to said printing means, a plurality of return amount memory means for respectively storing return amount values corresponding to said at least two types of recording paper, an interface for receiving a control command code for controlling a printing operation from a host computer, control command analyzing means for interpreting said control command code received from said host computer, first recording paper selecting means for selecting one of said at least two types of recording paper for which the return amount value is to be set based upon said control command code, second recording paper selecting means for selecting at least one of said at least two types of recording paper to be transferred by said recording paper transfer means based upon said control command code, and control means for controlling said plurality of return amount memory means for storing said return amount values corresponding to the recording paper selected by said first recording paper selecting means and for retrieving at least one of said return amount values corresponding to the recording paper selected by said second recording paper selecting means, said method comprising the steps of:
- receiving a control command code from said host computer;
- interpreting said control command code received from said host computer;
- selecting one of said at least two types of recording paper to be supplied to said printing means for said printing operation based upon said control command code; and
- storing a return amount value based upon a selected recording paper for controlling a return operation of said printing means between printing on successive lines of said selected recording paper.
