System A - (w8-FJ463AAR-ABA-a6528p); installed on an external hard drive; running on an HP6600 machine; first to be involved, and the only system to have the cups ppa version installed prior to the proposed version. System B - (w8u-iomega); installed on a second external hard drive; also running on the same HP6600 machine as System A. System C - (w8-Aspire-5000; a laptop); installed on the internal hard drive along with XP and Linux Mint. Testing 19Jan2012 1. System B (cups proposed installed); requested info collected in file named "SysB_cups1.5.0-8ub7_prop.txt". 2. Attempted to revert System B to cups ppa version without success; documented in file 91072_SysB_Revert.txt. 3. System C (cups proposed installed); requested info collected in file named "SysC_cups1.5.0-8ub7_prop.txt". 4. Attempted to revert System C without to cups ppa version success; documented in file 91072_SysC_Revert.txt. 5. System A (cups ppa version) printing tested; printed successfully. Requested info collected in file named "SysA_cups1.5.0-8ub7_ppa.txt". Installed cups proposed version through Update Manager. Attempted to print test file without success. Requested info collected in file named "SysA_cups1.5.0-8ub7_prop.txt". 6. Some screen shots collect along the way are attached. Comment - If I can determine how to get the ppa version installed on Systems B and C I will collect and submit the requested data. These installations are not currently involved in critical operations so can tolerate some abuse by a mostly novice. ** Attachment added: "SysA_cups1.5.0-8ub7_ppa.txt" https://bugs.launchpad.net/bugs/910272/+attachment/2683576/+files/SysA_cups1.5.0-8ub7_ppa.txt ** Attachment added: "SysA_cups1.5.0-8ub7_prop.txt" https://bugs.launchpad.net/bugs/910272/+attachment/2683577/+files/SysA_cups1.5.0-8ub7_prop.txt ** Attachment added: "SysB_cups1.5.0-8ub7_prop.txt" https://bugs.launchpad.net/bugs/910272/+attachment/2683578/+files/SysB_cups1.5.0-8ub7_prop.txt ** Attachment added: "SysC_cups1.5.0-8ub7_prop.txt" https://bugs.launchpad.net/bugs/910272/+attachment/2683579/+files/SysC_cups1.5.0-8ub7_prop.txt ** Attachment added: "91072_SysB_Revert.txt" https://bugs.launchpad.net/bugs/910272/+attachment/2683580/+files/91072_SysB_Revert.txt ** Attachment added: "91072_SysC_Revert.txt" https://bugs.launchpad.net/bugs/910272/+attachment/2683581/+files/91072_SysC_Revert.txt ** Attachment added: "19Jan12SysA125155.png" https://bugs.launchpad.net/bugs/910272/+attachment/2683582/+files/19Jan12SysA125155.png ** Attachment added: "19Jan12SysA151837.png" https://bugs.launchpad.net/bugs/910272/+attachment/2683583/+files/19Jan12SysA151837.png ** Attachment added: "19Jan12SysA152725.png" https://bugs.launchpad.net/bugs/910272/+attachment/2683584/+files/19Jan12SysA152725.png ** Attachment added: "19Jan12SysB113155.png" https://bugs.launchpad.net/bugs/910272/+attachment/2683585/+files/19Jan12SysB113155.png ** Attachment added: "19Jan12SysC132142.png" https://bugs.launchpad.net/bugs/910272/+attachment/2683586/+files/19Jan12SysC132142.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/910272 Title: USB->Parallel adapter produces crappy device URI and CUPS "usb" backend cannot cope with it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/910272/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
