AIX Version 4.3 Differences Guide

• Printer backend colon files for each printer data stream supported by the
printer.
• ODM parameters for the printer device driver and diagnostics.
• New message catalog entries for the printer name and new printer attributes
(if required).
• Packaging files to make support for the printer's separately installable
packages.

6.9.4 Print Job Administration Enhancements (4.3.2)
The print queue administration commands have been enhanced to support print
queues with more than 1000 jobs. Previous editions of AIX would allow more than
1000 jobs in a print queue. Cancelling or altering a job when the queue size grew
more than 1000 became difficult, because job numbers would repeat, and
specifying a specific job number would not guarantee that the job selected would
be unique and the one desired.
The formatting of the output of the qchk command, when used with the -W flag,
has been changed to show the six-figure print job number. The lpstat command
has been changed to also accept the -W flag to show information in wide format.
Use of the -W flag results in output where the lines are over 106 characters in
length. It can be quite confusing to read the output when using a screen that is
only 80 characters wide. To maintain compatibility for any user scripts that parse
the output of these commands, the default format for both remains unchanged
from previous versions.

The enq, cancel, qpri, qcan, and lprm commands have been altered to accept
six-figure job numbers.
The enhancement applies only to jobs submitted to local print queues. Jobs
submitted to remote printers will still have three digit print job numbers. This is
because of a restriction in the lpd protocol.
Although AIX 4.3.2 now generates six digit job numbers for local jobs, the
response time of the qchk and lpstat commands is identical to that on AIX 4.3.0.
The time taken to list the jobs on the queue is proportional to the number of jobs.
It is suggested that you maintain a queue size less than 1000 unless absolutely
necessary, because larger queue sizes will impact performance.
