The printer command “lpr” is a traditional command to print to a given printer. If no printer is specified, then it will print to a printer called lp
If you have KDE installed, then you can use the command “kprinter” instead of “lpq”. This will give you a second dialog box offering you various options on what to do with the printer's output. I don't know
Alternatively, tell lpq the name of the printer in the configuration settings:
lpq -P "printername"
You can also save to a file and just print that. Btw, Linux programs always print to files in postscript format.
