I cannot seem to get a USB Printer working on any qubes AppVM. -------------------
Printer does install without any problem, but print jobs immediately STOP. I am not seeing any CUPS errors other than generic filter failed. Printer is physically a Dell 1250c (but all Linux distros use a compatible Xerox Phaser 6010N driver). The driver comes as an rpm and a deb package, and includes the PPD files. I've tried both fedora-26 and debian-9 based VMs. I've tried attaching the USB device, and assigning the entire PCI USB Host Controller to that AppVM. I've tried reinstalling CUPS. I have an bare-metal Lubuntu system, that works fine with just the deb install. So I created an HVM via a Lubuntu 16.04.2 ISO, assigned the PCI USB Host Controller, and it works fine there too. -------------------- Current Workaround: Dedicated USB Host Controller for the printer, assigned to a 'printer' HVM, running CUPS on Lubuntu, and shared. sys-firewall iptables rule to ACCEPT port 631 on the FORWARD chain. Then install the printer pointing to the 'printer' vm. I figure this has to be a CUPS filter driver problem that is uniquely Qubes. If anyone has any suggestions, please let me know.
