Hi Folks, the reason: new printer HP LaserJet Pro M1132 MFP This printer needs a non-free plugin. On my 64-bit machine with CentOS 5.5 the installation via hplip-3.11.1.run and hplip-3.11.1.plugin.run works perfectly (except scanning - but that's not the problem at the moment). On my second machine - CentOS 5 32-bit I have many problems and printing doesn't works. 1. Installation using hplip-3.11.1_rhel-5.0.i386.rpm runs. But calling hp-setup or hp-check ends in warning: CUPSEXT could not be loaded. Please check HPLIP installation Calling ./hplip-3.11.1-plugin.run to install the non-free plugin ends with the same message. locate cupsext brings /usr/lib/python2.4/site-packages/cupsext.so 2. Installation via hplip-3.11.1.run ends in error: Configuration failed with error: libcups not found locate libcups /usr/lib/libcups.so /usr/lib/libcups.so.2 /usr/lib/libcupsimage.so /usr/libcupsimage.so.2 I've "goggled" a little bit and read that it could be a python-issue python -v Python 2.4.2 (#1, Nov 11 2010 13:34:43) [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on Linux2 same as on the 64-Bit machine. What goes wrong? Timothy
