Unbelievable: After years with Ubuntu-12.04 to 16.04, followed by Linux Mint up to 19.3 (Ubuntu 18.04), I switched to a fresh new install of Lubuntu-19.04 a week ago... and have this strange printer disappear problem for the first time ever! Today is May 18th, 2019 - that is eight years(!!!) after the last entry in this list. How can that be? What's wrong? -------------------------- My printing system for the last 12-15 years based on cups with the following setup: * 1 network laser printer * 3 "symbolic" printers which are a copy of the former, to set defaults for particular uses: "monoprinter" (grayscale), "colorprinter" (full color) and "labelprinter" (use of manual feed) # lpstat -s device for Brother_MFC_9142CDN: ipp://BRN30055C78CF3B.local:631/ipp/print device for colorprinter: ipp://BRN30055C78CF3B.local:631/ipp/print device for labelprinter: ipp://BRN30055C78CF3B.local:631/ipp/print device for monoprinter: ipp://BRN30055C78CF3B.local:631/ipp/print # ls -l ppd/ total 96 -rw-rw-r-- 1 root lp 8619 May 12 18:07 Brother_MFC_9142CDN.ppd -rw-rw-r-- 1 root lp 8619 May 12 18:07 Brother_MFC_9142CDN.ppd.O -rw-r----- 1 root lp 8617 May 17 21:00 colorprinter.ppd -rw-r----- 1 root lp 8635 May 17 20:56 colorprinter.ppd.O -rw-r----- 1 root lp 8622 May 17 21:05 labelprinter.ppd -rw-r----- 1 root lp 8622 May 17 21:01 labelprinter.ppd.O -rw-r----- 1 root lp 8620 May 17 20:59 monoprinter.ppd -rw-r----- 1 root lp 8635 May 17 20:58 monoprinter.ppd.O Besides the different settings in /etc/cups/printers.conf, the DeviceURI is the same for all four while the UUID differs: <Printer Brother_MFC_9142CDN> UUID urn:uuid:f81a64b6-71d2-3878-71cf-1b1fd6b4dba3 DeviceURI ipp://BRN30055C78CF3B.local:631/ipp/print </Printer> <Printer colorprinter> UUID urn:uuid:63efeecc-be6e-3065-6c0c-9a73bdd0dd62 DeviceURI ipp://BRN30055C78CF3B.local:631/ipp/print </Printer> <Printer labelprinter> UUID urn:uuid:756313d5-4548-327f-666b-9f2edf2c8942 DeviceURI ipp://BRN30055C78CF3B.local:631/ipp/print </Printer> <DefaultPrinter monoprinter> UUID urn:uuid:c4abcfb1-c1f2-34fd-4e8f-514209e3e5e9 DeviceURI ipp://BRN30055C78CF3B.local:631/ipp/print </DefaultPrinter> Any help / hint / solution is highly appreciated - TIA. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/577859 Title: printer disappears Status in cups package in Ubuntu: Confirmed Bug description: Binary package hint: cups some days ago I've done a fresh install of ubuntu 10.04. It's now the second time that when I try to print a document the printer has disappeared. In the box where one normally selects the printer there's only the option 'Custom...' Workaround: reinstallation of the cups package. After reinstallation the deskjet printer can be selected again.
