Disabeling LPT1 under XP

Is it possible to disable LPT1 within XP(software) without turning it of in the hardware.

I ask this because i’ve installed a hp laserjet 3100, installed the drivers, but XP keep finding new hardware on LPT1, the printer software created it’s own port HPL3100 and doesn’t use the LPT1 under windows.

When I set the printer manualy on the LPT1, XP will reboot when I try to print anything.

when it’s installed on the HPL port the printer works perfect, i can print,fax,copy,scan
