	Hello,

	I think that the umax_pp.conf has some unexpected keyword in it (such 
as 'device'), hence the 'don't know what to do with ...' messages. You only 
need these 2 lines in it:

option buffer 2097152
port safe-auto

	The log shows that parport communication is non-working.

	From your previous mail, I think your parallel port is OK:

    parport: PnPBIOS parport detected.
    parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP]
    ppdev: user-space parallel port driver:

	However, double check in BIOS that the parallel port settings are really 
these ones. You may force correct detection by giving the settings to the 
kernel module:
options parport_pc io=0x378 irq=7 dma=none

	An other option would be to set the parallel port to EPP+ECP in BIOS and
give the following option to the parport kernel module:
options parport_pc io=0x378 io_hi=0x778 irq=7 dma=auto

	The trouble with parallel ports are the bugs that affect hardware and BIOS. 
You have to find the best settings for your PC by trial and error. Be aware 
that the HP3200C might need to be reset after unsuccessful test (see 
http://umax1220p.sourceforge.net/tips.html for the procedure).

	The attached ppdiag script will let you test your parallel port. Send its 
output in EPP and EPP+ECP mode, that will let use see what could be the best 
hardware settings.

Regards,
	Stef
