Naah. It would rather be the other way round.

With questions like this, it helps *immensely* to not only know which
OS (HP-UX 11.11 here), but also which CUPS version is used.

What specific cupsd.conf instructions? How many print clients? Do
the clients poll, or does the server push its printer list to the
clients ("Browsing")? How many jobs are listed in /var/spool/cups/ ?
How much RAM is available on the system? Are there DNS issues in-
volved?

etc.pp. ....
