6.1.3 PRINT DATA PROCESSING
The key roles of each part of the print system are outlined below.
• The drivers are responsible for generating the page description on the host
system and for transmitting data to the printer.
• The I/O manager mediates the connection between the parallel port or
network interface and establishes a device or print manager connection.
• The print manager is responsible for spooling the job (if appropriate) and for
feeding jobs to the correct PDL interpreter.
•
The PDL interpreters are responsible for turning page descriptions into
rendered pages and for parsing job management comments.
•
The compression subsystem manages compressed pages in memory.
• The page manager coordinates pages for sending to the engine for the most
efficient printing, finishing, and accessory handling.
•
The video subsystem is responsible for decompressing pages and feeding
the engine with appropriate engine signals. The video subsystem also
handles certain print quality processing functions.
