If the anyone face printer related issue gets help from this https://www.epsonsupport247.com/steps-to-fix-epson-printer-error-code- 0x9a/ ** Attachment added: "printrtrrrrr.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/872711/+attachment/5212583/+files/printrtrrrrr.jpg -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/872711 Title: Kernel does not report some USB printers correctly, making them not being detected by CUPS Status in linux package in Ubuntu: Fix Released Status in linux source package in Oneiric: Fix Released Status in linux source package in Precise: Fix Released Bug description: See the following CUPS upstream bug report: http://www.cups.org/str.php?L3884 Users complain that their USB printers do not get detected by CUPS and so they cannot set them up for printing. In the last comment it is told that the kernel is the culprit and a link to a patch proposal on the Kernel mailing list is given: http://lkml.org/lkml/2011/9/25/57 The patch attached there is supposed to solve the problem. I have also a printer (HP Color LaserJet CM3530 MFP) which is only detected by the HPLIP CUPS backend (this backend uses another detection method but is only avaiolable for HP printers) and not by CUPS' own backend, so I can reproduce the bug. I did not test the kernel patch. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
