I have my logs set to wrap after 5m and I only keep 3 copies, but this is
pretty nasty, it continually runs lookups until lpd is killed and started

It's also a little unusual, I wonder why it keeps doing this.
Your urls give me a 404 too.

So, what configuration changes have you made to lprng?  I'm looking for
the printcap and the lpd.conf changes specifically.

Hello,

My printcap has been the same for the past 3-5 years, its not something
I ever changed once I got it working:

$ cat /etc/printcap |grep -v ^#


.common:
   :sd=/var/spool/lpd/%P
   :sh:mx=0:mc=0

hp:\
        # Printer log file.
        :lf=%P.log:\
        # The minimum number of lines required to print.
        :ml=0:\
        # Maximum job size.
        :mx=0:\
        # Maximum number of copies.
        :mc=0:\
        # Spool queue directory for temporary storage of print jobs.
        :sd=/var/spool/lpd/%P:\
        # Supress banners and headers.
        :sh:\
        # Spool queue accounting file.
        :af=%P.acct:\
        # Setup where we want to print to.
        :tc=.common:lp=192.168.168.250%9100:\
        #:tc=.common:hp=192.168.168.254%515:\
        #:lp=hp@192.168.168.254:\ works
        #:tc=.common:lp=hp@192.168.168.254:\
        # Setup the filter we want to use.
        :filter=/usr/lib/ifhp/ifhp:\
        # Specify the ifhp configuration options.
        :ifhp=model=hp2200,status,sync,pagecount,waitend:
        # Specify page options.
        :prefix_z=600,duplex,letter:

Justin.
