2. Printer controller

The printer controller manages print options, provides the user

interface, and runs system management and diagnostic

operations on demand. The following is an explanation of tasks

that enable the job to be printed:

• The printer controller detects which job protocol is being sent.

• Print option parameters are stored in the Job Pool Manager

(JPM) database, which maintains a database of all jobs. This

database contains a reference to the print data on the fixed

disk, as well as the print options parameters for the print data.

The JPM responds to the printer controller commands for

deleting, holding, and prioritizing jobs.

• Print data is stored on the printer controller disk for queuing

and while printing.

• When the printer controller begins processing a job, it sends

the print data to the decomposer. The decomposer converts

the print data into a bitmap in the resolution appropriate to

the printing device.

The decomposer utilizes font data from font files stored on

the printer controller disk or font information sent to the

printer controller with the print job.

• When processed data comes back from the decomposer, the

printer controller Device Driver transmits the print data and

print option parameters to the printer. Printing is then

initiated.

• After the job has been printed successfully, the print data file

is deleted from the disk. If an error inhibits job completion, the

printer controller manages the recovery and completion of

the job.

The system can manage the processing of multiple jobs and the

printing of another job simultaneously. When you are printing

IPDS jobs, the printer controller is able to queue multiple

PostScript and PCL jobs at the same time. When you are printing

PostScript and PCL jobs, you can send one IPDS job.
