[hpoj-devel] Problems wih hpoj 635c sourcecode

[Johan L. <j.l...@ch...>]

Hello all,

Recently I downloaded the sourcecode hpoj-0.6 for my
HP OfficeJet for working with it under RH Linux 6.2.

Now I have some problems with the software. I appriciate
some help solving these problems.

Problem 1.

Printqueue stops and LC panel is frozen dead when printing 
more than one job. When killing the xojpanel process 
printing resumes normal operation. I cut out some
messages for successfully loading the ieeedrivers and 
the messages where it goes wrong.

Problem 2.

I'd like to scan with the OfficeJet so I downloaded the
sane sourcecode and applied your patch. I followed your
instructions in the documentation. I discovered the two
lines: "checking for ptal.h... yes" and "checking for
ptalInit in -lptal... yes" while configuring.
When I make a test scan with scanimage --test the following 
errors are reported (I turned on some debug coding):

[johan@johan johan]$ scanimage --test

Is there someone who can tell me what is wrong and what
I have to do to solve the problems?
