Do you have the option of using an internal JetDirect card on this
printer?
What happens when you take out the "status@"? (Although I would have
chosen to use it myself, on an external JetDirect.)
Other feeble suggestions are to check the configuration of the LaserJet,
and make sure the parallel settings are high speed = yes and adv fnctns =
on. A nice new IEEE 1284 printer cable might help too. (The IEEE 1284
spec says the cable should be marked "IEEE 1284".)
Anything interesting in the log file for this print queue?

Subject: LPRng: still losing ends of jobs
I posted about this a while back, and I don't think anyone responded.
We're to a point where it's getting to be a *really* big problem, and I
have no idea what to do.
We're running LPRng 3.6.24 on RedHat 6.2, and our printer is
HP Laserjet 4 Plus. (We're using ifhp (3.3.17?), but for reasons given
below I'm fairly sure that the problem occurs after ifhp is done.
The printer has an external JetDirect box, and we print to port 9100.
We also print to this printer from a SysV Unix box, using the lpsched
system that came with it (but again printing to port 9100), and we do
not see this problem at all with it, ever.
The problem is that we lose the ends of jobs of more than a few pages.
The printout just stops at some point, usually in the middle of a page.
If the same job is sent again, it stops at exactly the same point.
Or at least it has done so in a number of tests.
Whenever this happens, the status readout on the printer is left showing
the username of the user who sent the job. This would appear to indicate
that the PJL commands to reset it are part of what's lost - which seems
reasonable on the face of it, after all.
In reading the HOWTOs, the only thing I could find that looked remotely
like it might relate was the socket_linger parameter. I've tried
boosting it way up there, with no change whatever.
I've set up a printer exactly the same except printing to file. I can
see that everything is there - stuff at the beginning added by ifhp,
the file being printed, and PJL commands at the end. If I move this
whole thing to the SysV box and send it (binary mode) to the printer,
the whole thing prints. It sure looks as though LPRng is the culprit.
Here's the printcap entry for the printer. (The "-Z land66hp" causes
ifhp to add some extra setup stuff at the beginning of the job. It
works fine for shorter jobs.)
laser:\
:sd=/var/spool/lpd/laser:\
:mx#0:\
:mc#0:\
:socket_linger#90:\
:sh:\
:lp=laser%9100:\
:ifhp=model=hp4plus,status@:\
:if=/usr/local/libexec/filters/ifhp -Z land66hp:
As I say, I've tried boosting the socket_linger up much higher, with
no result whatever.
As we're now setting things up so that this box is our print server
for all our PCs, this is very quickly going to be a solve-it-or-die
problem for me. I have no idea whatever to do about it. If anyone
sees anything I might be missing, please speak up quickly.
(And I sure hope Patrick is listening at this point.)
Thanks. <sigh sigh sigh sigh sigh>
