Can only print one document

[Brendan Simon <BrendanSimon@fastmail.fm>]

I'm running Debian testing (kernel-image-2.4.27-1-k7) with CUPS (cupsys 
and cupsys-bsd 1.1.20final) and I have an HP LaserJet 3330.

I have had it working with earlier kernels and cups but now it only 
prints one document and does not print subsequent documents.  If I use 
"lpr file.ps" it prints fine and the queues are empty.  If I run "lpr 
file.ps" again the printer says "Printing Document" but nothing happens.

Any ideas?  I've racked my brain and searched the internet but nothing 
has worked so far.  I'm at my wits end.

Please help.
Kind regards,
Brendan Simon.
