In the meantime you may like to try out my readymade RPMs:

I provide for testing HPLIP 1.7.4a for the released openSUSE 10.2
and Suse Linux 10.1 and Suse Linux Enterprise 10 (SLE 10)
and for the openSUSE development version openSUSE "factory"
for 32-bit Intel compatible (i586) and 64-bit AMD (x86_64)
via the openSUSE build service at
http://software.opensuse.org/download/home:/jsmeix/

The packages are
* only for testing
* without any guarantee or warranty
* without any support 

As an extreme example, this means that if your complete computer center
crashes because of these packages, it is only your problem.

Nevertheless, I am very interested in your feedback because the more
people test it, the more problems (even hidden problems) are revealed.
To send me feedback or bug reports, please follow the instructions in
http://en.opensuse.org/Submitting_Bug_Reports
Choose the component "Printing" (also for scanning/faxing with HPLIP).
Make it obvious which package, which package version, which hardware
architecture and which openSUSE version you are talking about - e.g.:
 "Feedback regarding hplip-1.7.4a-2.1.i586.rpm
  and hplip-hpijs-1.7.4a-2.1.i586.rpm from
  http://software.opensuse.org/download/home:/jsmeix/ 
  for openSUSE 10.2 used on 64-bit AMD hardware."
Ideally provide the "rpm -q --changelog hplip | head" output
to make it obvious which exact package release you have.


Regarding the parallel port:

There are some bug reports about problems with the parallel port
in our Novell/Suse Bugzilla. A good report to start is
https://bugzilla.novell.com/show_bug.cgi?id=185135
See also the other bug reports which are mentioned there.

The current workaround is to experiment with various BIOS settings
and explicite additional settings in /etc/modprobe.conf to find a
setup, which actually works in a particular problematic case.

Note that e.g. for scanning you may have to use a higher-level
parport mode (some kind of fast bidirectional mode)
and additionally the kernel module ppdev may have
to be loaded for all-in-one devices, see
http://hplip.sourceforge.net/tech_docs/overview.html
regarding "MLC/1284.4".

Note that those modes (EPP or even ECP) normally require
an interrupt and ECP additionally requires DMA.
To activate the interrupt mode, set in /etc/modprobe.conf
something like "options parport_pc io=0x378 irq=7"
where io and irq must match to your BIOS settings.
Make sure that the IRQ which you use for the parallel port
is not used by any other stuff (check /proc/interrupts) and
see our online documentation (package suselinux-manual_en
or opensuse-manual_en) chapter "Printer Operation",
section "Troubleshooting", sub-section "Parallel Ports".


Kind Regards
Johannes Meixner
