No, but it would explain why nothing gets printed! This should be written by 
the lpadmin command at the end of cmd_node_addprinter in nxnode and should 
match the DEVICE_URI specified. It would be worth finding out what parameters 
it is actually using, then running the command manually from within a session 
to see if any errors occur, and if it gives the same result.

lpinfo should be able to tell you about the configured printer and lpr should 
be able to send jobs to it. I don't use either often enough to say which 
switches to use. You could also enable browsing in the cups config in nxnode, 
then point a browser at it on the port 9000+display to get the normal cups 
web interface - this used to work. 

Slightly OT: I see we're still modifying KDE_PRINTRC with perl. I probably 
forgot to mention this before, but can we use kwriteconfig instead? We could 
replace the egreps, echos end perl regexp evaluation with:
  [ "$ENABLE_KDE_CUPS_DYNAMIC" = "1" ] && 
$COMMAND_KWRITECONFIG --file="$KDE_PRINTRC" --group=CUPS --key=Host '"$PATH_BIN/nxcups-gethost"' 
  [ "$ENABLE_KDE_CUPS_DYNAMIC" != "1" ] && 
$COMMAND_KWRITECONFIG --file="$KDE_PRINTRC" --group=CUPS --key=Host 
$NODE_CUPSD_SOCKET
