	Hello,
	for the first point, it is likely that your parallel port isn't set to EPP.
Check the BIOS first, then look in system messages if your parallel port is 
correctly detected. For instance, on my system I have (when I boot with scanner and
printer powered on):
root:/root>dmesg|grep parport
parport0: PC-style at 0x278, irq 5 [PCSPP,TRISTATE,EPP]
parport0: faking semi-colon
parport0 probe: warning, class 'IMAGE' not understood.
parport0 (addr 0): Unknown device, UMAX Astra 1220P
parport0: Printer, EPSON Stylus COLOR 440
lp0: using parport0 (interrupt-driven).

	Note that if you don't have EPP or ECPEPP listed, the scanner won't work.	
	
	For the second point, the umax_pp backend is not activated in default 
install. You have to edit 'dll.conf' (which is usally located in /etc/sane.d or 
/usr/local/etc/sane.d) and remove the '#' at the start of the line '#umax_pp'.
