Hello Shakil! In fact, my first sentence is a little confusing. It's not a problem related to Acrobat Reader (A.R.), but initially I thought, that if you change the colour settings of HPLIP within A.R. (for example), HPLIP keeps these settings for all other apps. Now that I tried everything again, I found out that this is not true and that this was not the cause of the problem. But this does not mean that there is no problem. It's only more complicated. Ready? If you change to grey scale within HPILP one of the few programs which causes the problem directly is Word via Wine; obviously because Word/Wine uses the settings of HPLIP and you won't notice that, since there is no possibility to change these setting inside the printer dialogue of Word. Another program which respects the settings of HPLIP is Mozilla Firefox. If you change to grey scale inside HPLIP, Firefox will print grey scale causing the problem. If you tell Firefox to print in colours, it will do that correctly, but if you try to print another page out of Firefox it will have changed already back to grey scale. With GEdit it's exactly the same: I printed a file with the word "test" with the same result/problem. A.R. and OpenOffice, instead, seem to ignore the settings made via the HPLIP tray icon. Colour is chosen by default or, if not, you can choose "color" within the printer dialogue of A.R. and/or OpenOffice and both apps will print fine in colours and will keep these settings. But if you change there to grey scale you can cause the problem even with A.R. and OpenOffice. However, if you change to greyscale, there's a workaround to avoid the problem: If you tell HPLIP or the program you are printing with, that only the black cartridge is installed, it will print grey scale correctly (I didn't discover this last time!). After I found all this I tried to do what you ask me to do: First I made the hp-check-log (see below). Than I opened http://hplipopensource.com/node/225 and followed the instructions, but with no success. Here is what i have done in a Terminal: rennie@Riese:~$ # /etc/init.d/cups restart rennie@Riese:~$ sudo /etc/init.d/cupsys restart [sudo] password for rennie: sudo: /etc/init.d/cupsys: command not found rennie@Riese:~$ sudo /etc/init.d/cupsys restart sudo: /etc/init.d/cupsys: command not found rennie@Riese:~$ sudo /etc/init.d/cupsys restart sudo: /etc/init.d/cupsys: command not found rennie@Riese:~$ sudo /etc/init.d/cups restart * Restarting Common Unix Printing System: cupsd [ OK ] rennie@Riese:~$ tail -f /var/log/cups/error_log E [08/Oct/2009:13:53:41 +0200] Resume-Printer: Unauthorized After that the terminal window hangs. Do you now what's the problem? ============================================================================================================ HP CHECK LOG ============================================================================================================ hp-check[31644]: info: : Initializing.
