Printer for managing a plurality of print job data

A recording medium recording a program to realize a predetermined function for a printer having an exclusive interface connected to a host machine by an exclusive line connection, said program comprising:

• an extracting function for extracting, on a job-unit basis, print job data from among a series of reception data received from said host machine through said exclusive interface;
• an assigning function for assigning identifying information to the extracted print job data;
• a spool function for outputting print job data assigned with the identifying information to a predetermined memory unit and reading out same in a predetermined order;
• a generating function for imaging the print job data read out by said spool function and generating image data;
• and
• a print control function for supplying the generated image data to a print engine.

A method for managing print job data comprising steps of:

• a step of accepting a series of reception data from a host machine through an exclusive interface;
• a step of extracting, on a job-unit basis, print job data from among the series of reception data accepted;
• a step of assigning identifying information to the extracted print job data;
• and
• a step of managing respective ones of the print job data on the basis of the assigned identifying information.

A method for controlling a printer having an exclusive interface to be connected to a host machine by exclusive line connection, comprising steps of:

• a step of extracting, on a job-unit basis, print job data from among a series of reception data received from said unit through said exclusive interface;
• a step of assigning job identifying information to the extracted print job data;
• a step of outputting print job data assigned with the job identifying information to a predetermined memory unit and reading out same in a predetermined order;
• a step of imaging the print job data read out by said spool function and generating image data;
• and
• a step of printing to a print recording medium on the basis of the generated image data.

A print system configured including a host machine and a printer, comprising:

• said host machine having
• first transmitting means for transmitting a print request based on application data to said printer;
• first job managing means for transmitting a predetermined job manage request in response to the print request transmitted to said printer, and accepting job management information transmitted from said printer and controlling to display the accepted job management information on a screen;
• said printer having accepting means for accepting the print request as a job;
• issuing means for issuing identifying information for the accepted job;
• generating means for generating image data based on the print job data, as a process for the job;
• printing means for printing to a print recording medium on the basis of the generated image data, as a process for the job;
• second job managing means for managing the accepted jobs in plurality on the basis of the identifying information;
• wherein said second job managing means controls at least of any of said first accepting means, said generating means and said printing means to suspend a process for a particular job where said first job managing means transmits a job manage request to cancel the particular job.

A print system configured including a host machine and a printer, comprising:

• said host machine having
• first transmitting means for transmitting a print request based on application data to said printer;
• first job managing means for transmitting a predetermined job manage request in response to the print request transmitted to said printer, and accepting job management information transmitted from said printer and controlling to display the accepted job management information on a screen;
• said printer having
• accepting means for accepting the print request as a job;
• issuing means for issuing identifying information for the accepted job;
• generating means for generating image data based on the print job data, as a process for the job;
• printing means for printing to a print recording medium on the basis of the generated image data, as a process for the job;
• second job managing means for accepting a status of a process for the job notified from at least any of said first accepting means, said generating means and said printing means;
• wherein said second job managing means transmits a status of a process for the job to said first job managing means where accepting a status of a process for the job.

A method for controlling a printer, comprising steps of:

• a first step of accepting a job in a form of print job data from a host machine;
• a second step of generating image data on the basis of the print job data, as a process for the job;
• a third step of printing to a print recording medium on the basis of the generated image data, as a process for the job;
• wherein the printer controlling method further includes a step of issuing identifying information for the job accepted in the first step and a step of managing the accepted jobs in plurality on the basis of the identifying information.
