[lug] RE: Printing Problems

[Brian Armstrong]

Dear All,

    This is a comment on the JetDirect / No Daemon Present problem
described by Ed Young below.
    On 2 stations running RH 6.1 with HP JetDirect 170X boxes connected
to HP 1100 laserjet printers
    I had the problem described by Ed below.

    It appears that the lpd forked to print the job died before deleting
one of the cfXXX files
    created in the spool directory (there are two cfXXX files,  the
other, and the dfXXX files are all deleted
    when the print job completes).

    The problem is somehow intermittent, and I don't know what causes
it.

    Ed suggested `lprm -' (see below)  which seems to have cleared up
the problem on one machine but
     not the other.

    On the resistant machine,  if I install   lpr-0.48-1.i386.rpm    the
problem goes away.
    But if I reinstall  lpr-0.41-2.i386.rpm, which came with the 6.1
distribution, the problem comes back.

    If anyone has this symptom, I suggest upgrading lpr (the RPM
includes lpd).

    If anyone knows what causes this, I'm curious.

Cheers,
Brian

I figured out how do fix the problem, but I don't realy know exactly
what caused it.

I simply removed all the jobs that i owned with "lprm -" (See the man
page for lprm)

lprm(1)
    -       If a single `-' is given, lprm will remove all jobs which a
user
             owns.  If the super-user employs this flag, the spool queue

will
             be emptied entirely.

This fixed the problem. Didn't I post that as the resolution?
