- The lp driver changed to a new tunable driver somewhere in pl5-6 time. You
- need a command called tunelp and need to tune to your lp (the default
- values chosen at boot time seems to be way off for deskjet 500.) Here is
- what I use with my 500 and works just fine.
-
- tunelp /dev/lp -w 0
- tunelp /dev/lp -c 350
- tunelp /dev/lp -t 5
