Very slow printing with stock FreeBSD5.3 + CUPS + Gimp-Print + HPDeskJet612C

[Anthony M. Agelastos]

I forgot to mention that after the first reply to my thread by John, I 
turned the resolution down to 150x150 (the lowest it would go) and 
black and white (not even grayscale). Putting the interrupt at 5 as 
opposed to 7 allowed for one whole test page to print straight through. 
Turning the quality to 300x300 grayscale promoted the same problem with 
the dmesg message:

Interrupt storm detected on "irq5: lpt0"; throttling interrupt source
