Setting Your Preferred Default Printer
The HH-303 HPLJ M630 is the default printer on most systems. You can change the default (the printer used when no -P option is given to lpr, and the printer automatically selected by kprinter) by adding a line like the following to your .cshrc file:
setenv PRINTER HH303-HPLJM630
This change will take effect after you log out and back in.
