Two things, Miro...

1.  Where is your printer card?  This is a IIe?  Open the cover and look. 
The printer card should be in Slot #1 (left-most) under most
circumstances.  It may be that you are simply lucky that it is printing at
all.  The command is "PR#n" where n is the slot number.

2.  The line numbers are coming from the Applesoft "TRACE" command.  The
NOTRACE command will get rid of them.

The fact that the PR#n command seems to be triggering TRACE suggests that
perhaps you have no card at all in slot #6, so that when you issue the
PR#6 command, the computer gets confused and somehow goes through the
TRACE command before finally finding the routine to start printing.

It's just a guess...Good luck!
