Hi all,

   After reading this I have also updated the patch for SANE 1.0.13 but
until Saturday at the afternoon I can not test it.  Can anybody here
that owns an hp4200c scanner and is capable of patching and compiling
SANE 1.0.13 test this stuff before Saturday?

   You can download the patch at


http://hp4200-backend.sourceforge.net/sane-backends-1.0.13-hp4200-0.4.patch.gz

   I would love to see the backend integrated into the official SANE
distribution to avoid continuous patches after every new SANE relase
(SANE releases are much faster than me :P)

  More support will come after using the scanner again, sorry.

  Till: thanks for your effort!
