Hi,

the document you can print by "lp" command is pdf or ps type as the cups 
testpage is?

can you show your working "lp" commandline?

I can only remember one situation like this, there cups correctly was 
sending the jobs , but the printer didn't understand the printfile 
format. So the files "vanished" in cups (found then in the "finished" 
folder). The printer began to load the job (LED flashing) and shortly 
after that stopped flashing and that was all.
