I have a umax astra 1220P parallel port scanner.  Kernell info:

Linux trc2.bob-n.com 2.4.16 #3 Thu Dec 13 21:14:10 CST 2001 i686 unknown

Running on rehat 7.2, kernel upgraded from www.kernel.org

I've got sane 1.06, with the umax_pp patch umax1220p-2.5.

When I probe the scanner I get:

# /usr/local/src/sane-backends-1.0.6/tools/umax_pp -p -t 1
[sanei_debug] Setting debug level of umax_pp_low to 1.

[umax_pp_low] *** It appears that EPP data transfer doesn't work    ***
[umax_pp_low] *** Please read SETTING EPP section in sane-umax_pp.5 ***

I've already set the parallel port to EPP 1.7 in the BIOS.

Anyone have any ideas on this?

One SPECIFIC question:  wil this work with any db25 to db25 cable that
carries all the pins or do I need some special cable (ieee 1284?)?
