Subject:   lpt0 "device busy"
Message-ID:  <>

Just recently I've started having a problem with my HP 5N it was printing 
fine. Now, whatever I do lpt0 shows "device busy". I've googled reinstalled 
apsfilter and put the printer through all the self tests (passed) and verified 
there's nothing in the printer's memory. I've rebuilt userland and kernel. 
Even tried cups and anything sent to /dev/lpt0 returns that error.

fstat /dev/lpt0 and fstat /pt0.ctl show nothing.

Ant attempt at changing settings with lptcontrol also result in a "device 
busy" error. 

pinnacle# lptcontrol -p -d /dev/lpt0.ctl
lptcontrol: open: Device busy

I'm totally at a loss to figure out what's changed does anyone have any 
suggestions? I really need to get this working.
