I just followed up before I read your message and actually the answer to your question is YES, the device does support multiple cartridges, in Windows the printer use both cartridges to print a page which has multi- colours and it is clear that the device does support the feature. Under Linux the black text is blurred and not so black when printing pages in colour mode. It's a real nuisance and pain to see colour wasted and the output so bad compared to when using the black cartridge. -- Harishankar (http://harishankar.org http://lawstudentscommunity.com) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
