Hi Till, Quick summary and then the data dumps: 1) Applied lpadmin -p <printer> -o usb-unidir-default=true and power cycled 2) It printed successfully about 6 times. No errors. YAY! 3) I then reset all defaults and power cycled printer again 4) It then failed half way through last page of a six page document. Please note that I have a very long USB cable maybe 15m.
Dumps as requested. There seems to be a keyring problem but only a warning. panamagold@panamagold:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc.
