I don't understand what's happening with this printer. Turning off USB-reattaching helps but not too much. No we can print mo jobs until printer will disconnect. Could the issue be in printer hardware? Some time ago it was broken and then repeared at the service center. So the only idea I have is to check it with windows computer. Any other suggestions? Thanks. P.S. So using /usr/share/cups/usb/org.cups.usb-quirks now is not necessary as I understood. ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Changed in: cups (Ubuntu) Status: Incomplete => New -- 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/1495971 Title: Samsung ML-1250 prints only first job and then disconnects Status in cups package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: We have: lsusb Bus 004 Device 009: ID 04e8:300e Samsung Electronics Co., Ltd Laser Printer Just connected printer and started to print first job: tail -f /var/log/syslog Sep 15 14:50:18 desktop udev-configure-printer: URI matches without serial number: usb://Samsung/ML-1250 Sep 15 14:50:18 desktop udev-configure-printer: No serial number URI matches so using those without Sep 15 14:50:18 desktop udev-configure-printer: URI of detected printer: usb://Samsung/ML-1250, normalized: samsung ml 1250 Sep 15 14:50:18 desktop udev-configure-printer: URI of print queue: usb://HP/LaserJet%201200?serial=00CNCF203187, normalized: laserjet 1200 serial 00cncf203187 Sep 15 14:50:18 desktop udev-configure-printer: About to add queue for usb://Samsung/ML-1250 Sep 15 14:50:20 desktop udev-add-printer: add_queue: URIs=['usb://Samsung/ML-1250'] Sep 15 14:50:20 desktop udev-add-printer: D-Bus method call failed: org.freedesktop.DBus.Error.ServiceUnknown: The name com.redhat.NewPrinterNotification was not provided by any .service files Sep 15 14:50:23 desktop udev-add-printer: PPD: foomatic-db-compressed-ppds:0/ppd/foomatic-ppd/Samsung-ML-1250-pxlmono.ppd; Status: 0 Sep 15 14:50:24 desktop colord: Profile added: ML-1250-Gray..
