Well, I did as Rick mentionned
eog prints in no time into output.ps
foo2lava-wrapper takes 43 seconds (which is okay compared to the 39 seconds of Rick)
and the printer takes no time to receive the data and to print it. (->no problem with my network)
I try to print from GIMP, and it takes a looong time again (26 minutes) but finally prints (see error_log _44 for details)
