Abstract:
A print control apparatus for outputting, to a printer engine, bit map data based on a print command, the print command includinga command representing information for developing characters, figures, or images to bit map data, and an attribute parameter representing a format for developing characters, figures, or images relating to the command to bit map data, the print control apparatus comprising: a first buffer which stores the print command; a second buffer which stores bit map data for at least two pages; a processor section which reads the print command from the first buffer, performs development to bit map data based on the print command thus read, and stores the bit map data thus developed in the second buffer; a page buffer control section which manages the second buffer on a page unit basis, designates a page of the second buffer in which the processor section is to store the bit map data thus developed, and designates at least one page of bit map data stored in the second buffer which is to be outputted to the printer engine; and a printer control section which controls the printer engine, monitors a state of the printer engine, detects a page discharge abnormality in the printer engine, detects a recovery of the page discharge abnormality, and performs a reprinting process after the recovery of the page discharge abnormality; wherein the processor section stores the bit map data thus developed in the page of the second buffer designated by the page buffer control section; and wherein when the printer control section detects the recovery of the page discharge abnormality, the printer control section reads from the second buffer bit map data of at least one page designated by the page buffer control section which has not yet been discharged from the printer engine, outputs the bit map data thus read to the printer engine, and performs the reprinting process.
