CUPS vs lp: Cannot print from acroread

[Peter Robinson <peter.robinson@t-online.de>]

Hi all,

I am having problems printing from acroread. I have set up a HP 1320 
laser printer using CUPs, and can print PDF files from KPDF without any 
problems.
When I try to print from acroread, my system gets sluggish for 10-15 
secs (although top shows nothing very unusual during this time) until 
finally the print dialog of acroread appears. After I click on "print" 
one sees the job getting sent off to the printer, but the job lands in 
nirvana and nothing gets printed.
Using the CUPS/manage jobs page at localhost:631, I see no new job.

If I enter lpq, bash tells me

lpq
lpq: lp: unknown printer


Could someone point me in the right direction?

Thanks a lot, Peter
