Lets try this. Open a terminal program. Type lpstat -tl and hit return Copy and paste that into an email. Then, type ls | lpr and hit return, then immediately hit the up arrow twice and hit return again. That's a vertical bar or pipe symbol between ls and lpr, not a number one or a small L. It's close to the return key on a US keyboard, but judging by your name you quite possibly aren't using one of those. Copy and paste that output into the email, and check the printer to see if it printed anything.
