Re: TCP/IP printers

Being a PC Network manager I'm not sure that I would answer the question of
TCP/IP printing problems with "just something you have to live with".  We
have some HP LJ4, 4+, 5, and 4000N's, some with external jet directs and
some with internal.  Varying amounts of memory, timeout settings vary widely
(something we've played with).  Some of our printers have both Novell print
queues and AS400 TCP/IP based connectivity, and some are serviced directly
by tcp/ip from NT workstations running jetprint, some are serviced by our
RS6000's using AIX with TCP/IP.  There doesn't seem to be any rhyme or
reason, some of these printers are connected only to the AS400 and no other
service and still do it.

We have a 100MB switch that services our server farm, and then we drop into
our backbone fiber switch which delivers 10MB to the racks that distribute
to the workstations and printers @ 10MB, we also have a frame relay network
with printers on the remote sites that do the same thing.

It seems to me to be a spooling issue of some kind.  We see it primarily
with the larger jobs that we run.....
