Queue is disabled, paused

[Dane Miller]

Hello,

Frequently a CUPS queue stops on my Debian Sarge box and jobs pile up until the queue is 
enabled.  I sometimes must cancel the offending job to enable the queue, other times a 
simple 'enable' works, and the offending job prints.  I haven't found the pattern.  In 
every case the error_log reports "Unable to send print file to printer: Connection reset 
by peer".

The printers are HP LaserJet 2100's. CUPS prints to them via socket://10.56.28.xx:9100.  I 
have tried "HP LaserJet Series CUPS v1.1" and "HP LaserJet 2100 Foomatic/pxlmono" 
configured via the web interface (aside, are these drivers, PPDs, filters, all of the above?).

This topic has come up recently:
http://www.cups.org/newsgroups.php?s2400+gcups.general+Gcups+v2403
http://www.cups.org/newsgroups.php?s2490+gcups.general+Gcups+v2497

Here are error logs with trimmed timestamps to fit email width.  I've also included links 
to the full debug level output.
