Anybody here have experience with cups and system v lp print queues? I have been asked to build a Perl solution, according to the following:
[1] A printing company has switched from SysV lp to cups. They have a
plethora of tools they have developed to query and manage lp queues;
which do NOT work with cups. However, their worst problem is the
tens of thousands of jobs they have queued, and the way cups
regularly polls queues, ALL queued jobs, and consumes an inordinate
amount of system resource.
[2] I have been asked to develop two (2) custom processes:
[A] A process to receive print job contents on STDIN, and build
System V lp queues, which can be managed by their existing
tools.
[B] A process to receive a print job request on STDIN, from which
this process will select the appropriate queues (as built in
[A]), and insert that print job into cups.
[3] Are there ways that cups can better manage large queues (as outlined
in [1])?
[4] What are the pluses and minuses of the approach in [2]?
[5] Where can I get more information on queue building, as outlined in
[2][A]?
[6] Is there a CLI to cups? Where is this documented?
I am not a printing expert -- for me, it simply works. However, I am an
accomplished programmer, especially Perl; and I need to establish the
scope of such a project, in order to quote it to my client.
What do you think?
