cups parallel backend hang up

[Géczi Szabolcs]

hi there,

i just recently installed cups, and i've tried to setup the printer.
but, anytime i start the cups the parallel backend hang up and cups 
stops startin' up.
here is my dmesg output:

ppc0: <Standard parallel printer port> port 0x378-0x37f irq 7 on acpi0
ppc0: Generic chipset (EPP/NIBBLE) in COMPATIBLE mode
ppbus0: <Parallel port bus> on ppc0
ppbus0: IEEE1284 device found /NIBBLE/ECP
Probing for PnP devices on ppbus0:
ppbus0: <Hewlett-Packard hp LaserJet 1320 series> PRINTER 
PJL,MLC,BIDI-ECP,PCL,POSTSCRIPT,PCLXL
lpt0: <Printer> on ppbus0
lpt0: Interrupt-driven port
ppi0: <Parallel I/O> on ppbus0

any idea?
another question, could anyone print with hp laserjet 1320 on usb port?

thx
