Bug Description

While trying to get my scanner working I hit this python error:

Hello,

Are you having a custom build of HPLIP? I mean to say, have you built HPLIP on your own, or using the HPLIP package supplied by the Distro?

Basically, parallel port support is disabled by default and won't be available unless one re-builds HPLIP with the parallel port option enabled.

You can goto the folder where you have downloaded and install hplip-3.11.12.( May be in ~/Downloads/hplip-3.11.12). Run in teminal
$ ./configure --prefix=/usr --enable-pp-build
$ make
$ sudo make install

For scanning, you can also use 'xsane'.

Please provide the output of 'hp-scan -g'.

Hi,
  yes it is a custom build, actually a build of a package under Gentoo Linux.
Here is the configure commandline:

./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/usr/lib64 --disable-dependency-tracking --disable-cups11-build --disable-lite-build --disable-foomatic-rip-hplip-install --disable-shadow-build --disable-qt3 --with-cupsbackenddir=/usr/libexec/cups/backend --with-cupsfilterdir=/usr/libexec/cups/filter --with-docdir=/usr/share/doc/hplip-3.12.2-r1 --with-htmldir=/usr/share/doc/hplip-3.12.2-r1/html --enable-dbus-build --enable-hpcups-install --enable-cups-drv-install --disable-cups-ppd-install --enable-hpijs-install --enable-foomatic-drv-install --disable-foomatic-ppd-install --disable-doc-build --enable-fax-build --enable-pp-build --enable-scan-build --disable-network-build --enable-udev-acl-rules --enable-gui-build --enable-qt4 --enable-policykit

  I can use the scanner when having no ECP on the parport (otherwise there
are too many IRQ triggers and the machine locks up after few seconds).
But this is NOT what I reported here. The python-based code needs some fix
not to get into the trap. Thats all.

Thanks,
Martin

This file has the fix for this issue.

In line #275, "return" is added.

Please go to the folder when you run "configure" and "make". Copy this file sane.py to /scan/ folder.

Run in terminal "make" and "sudo make install".

Hope this would solve your issue.

Hi,
  for completeness on the hardware side I am attaching to this bug my
(still unanswered) to linux-parport mailing list. I would be very grateful
if you have any comments/explanations on the kernel module options I could
try.
Best,
Martin

The printer works but scanning worked just once in ECP mode. I couldn't
get the card to be showing EPP mode. In the ends, I found the patch at
http://lists.infradead.org/pipermail/linux-parport/2010-April/000688.html
and can confirm this enabled me to get EPP detected (the patch applies to
linux-3.2.2 with some ...
