I can confirm that the bug is still present in the Ubuntu 18.04.4 LTS for my Canon MX300 An yes, the command sudo lpadmin -p MX300 -o usb-unidir-default=true seolves the problem.

Now it fails every single job, printing half a page and then ejecting the page when a USB reset is issued. Same printer works fine when printing through Windows in Virtualbox with USB passthrough. Summary: the USB backend "improvements" have rendered my printer useless with CUPS. Unloading the usblp module makes no difference - the USB reset is what aborts the print job. [ 224.008042] usb 3-1: reset full-speed USB device number 3 using uhci_hcd [ 224.161701] usblp0: USB Bidirectional printer dev 3 if 0 alt 0 proto 2 vid 0x04A9 pid 0x108 Kubuntu 12.04 [IMPACT] Everyone with a Canon inkjet connected to USB and also users of some other printer models on USB get printouts with the last page being incomplete. This happens for every job. For everyone with a Samsung printer the problem of bug 995111 shows up again. [TESTCASE] Unfortunately, for reproducing this bug one needs the actual hardware. Connect a Canon inkjet (or other models mentioned in this bug report) to the USB and print from a completely updated Precise system. The last page of each job will come out incomplete. Connect a Samsung printer to the USB and print from a completely updated Precise system. You will get printouts with weird characters (at least from the second job on) as described in bug 995111. After installing the proposed package all these problems should disappear. [Regression Potential] Regression risk is very low. The fix is not doing the USB device reset on the printer after the job for most printers. The fix contains an exception rule for Samsung printers and Prolific Technology USB->Parallel adapters, to avoid reoccurring of bug 987485 and bug 997040. It is still possible that some printers are treated incorrectly in terms of whether they need a reset after the job or not. As most printers work both with and without reset this risk is very low. All reported problems are solved with the proposed fix. ******* dpkg -l "*cups*"|grep ii ii bluez-cups 4.98-2ubuntu7 Bluetooth printer driver for CUPS ii cups 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - server ii cups-bsd 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - BSD commands ii cups-client 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - client programs (SysV) ii cups-common 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - common files ii cups-filters 1.0.18-0ubuntu0.1 OpenPrinting CUPS Filters ii cups-ppdc 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - PPD manipulation utilities ii ghostscript-cups 9.05~dfsg-0ubuntu4.1 interpreter for the PostScript language and for PDF - CUPS filters ii libcups2 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - Core library ii libcupscgi1 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - CGI library ii libcupsdriver1 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - Driver library ii libcupsfilters1 1.0.18-0ubuntu0.1 OpenPrinting CUPS Filters - Shared library ii libcupsimage2 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - Raster image library ii libcupsmime1 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - MIME library ii libcupsppdc1 1.5.3-0ubuntu2 Common UNIX Printing System(tm) - PPD manipulation library ii printer-driver-hpcups 3.12.2-1ubuntu3.1 HP Linux Printing and Imaging - CUPS Raster driver (hpcups) ii python-cups 1.9.61-0ubuntu2 Python bindings for CUPS ii python-cupshelpers 1.3.8+20120201-0ubuntu8.1 Python modules for printer configuration with CUPS ********** To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1032456/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
