i use my laptop to print on my laserjet, and it works by default settings, 
but

/usr/sbin/lptcontrol -d /dev/lpt0.ctl -e

make it much faster.

what i have (i don't disable interrupt)

ppc0: <ECP parallel printer port> port 0x378-0x37f,0x778-0x77f irq 7 drq 1 
on acpi0
ppc0: SMC-like chipset (ECP/EPP/PS2/NIBBLE) in COMPATIBLE mode

check BIOS settings too.
