Printing Questions

[Robert S. White]

There are a couple of things about HP-UX print services that have remained a mystery to me for years. Perhaps someone can shed some light.
1: On a system without jetadmin, jetdirect, etc. where is the printer name to destination information stored? Some printers have this information recorded in their lp/interface files. But some do not.
2: What is the purpose and what causes a file to end up in the /var/spool/lp/request/PDRequest directory on hosts that do not have HPDPS installed?

Hi Robert:

If I understand your question (1): If the device is not /dev/null (i.e. not a network/remote printer) then the output device is stored in /var/spool/lp/member/printer_xxx

The printers in question are remote. The information is not stored in model files.

I can answer or at least give some clue on question 2)..

I think 2 reasons why PDRequest dir exist..
1) So that print jobs from any HPDPS printers are spooled to this directory.
2) To resolve the problem of too many statfs() errors being logged in /var/adm/lp/lpd.log.

hope this helps ..

The information is also not stored in member files nor any other files under /var/spool/lp

Hi Robert,

I think the Lp destination is stored in /etc/lp/member.

The lp interface file only contains the lp interface script about the way the spooler interacts with the printer. It varies from model to model.

Hope this helps.

The LAN does not have any HPDPS printers. None of the servers/workstations have HPDPS software installed. I am curious as to the second thought. Why would a file be transferred to the PDRequest directory rather than a message sent to the print log?
