In another thread, I cut and pasted this from the Debian 11 release notes ref CUPS I did not get a chance to pre-read any of that, one of seacrates not so illustrious and only a few months old shingled 2T drives drowned in its own puke in the night 10 days ago and its taken 7 installs to get as far as I have so far. This time of 5 SSD's, 4 of them making a 2T raid10 for /home. 2.2.2. Driverless scanning and printing Both printing with CUPS and scanning with SANE are increasingly likely to be possible without the need for any driver (often non-free) specific to the model of the hardware, especially in the case of devices marketed in the past five years or so. The printer in question is about that old, its a Brother MFC-J6920DW. Big, it can do tabloid including the scanner but feeding it is a PITA.. 2.2.2.1. CUPS and driverless printing Modern printers connected by ethernet or wireless can already use driverless printing, implemented via CUPS and cups-filters, as was described in the Release Notes for buster. Debian 11 “bullseye” brings the new package ipp-usb, which is recommended by cups-daemon and uses the vendor-neutral IPP-over-USB protocol supported by many modern printers. This allows a USB device to be treated as a network device, extending driverless printing to include USB-connected printers. The specifics are outlined on the wiki. The systemd service file included in the ipp-usb package starts the ipp-usb daemon when a USB-connected printer is plugged in, thus making it available to print to. By default cups-browsed should configure it automatically, or it can be manually set up with a local driverless print queue. I cannot see any such ipp-usb file running in a root htop session. 2.2.2.2. SANE and driverless scanning The official SANE driverless backend is provided by sane-escl in libsane1. An independently developed driverless backend is sane-airscan. Both backends understand the eSCL protocol but sane-airscan can also use the WSD protocol. Users should consider having both backends on their systems. eSCL and WSD are network protocols. Consequently they will operate over a USB connection if the device is an IPP-over-USB device (see above). Note that libsane1 has ipp-usb as a recommended package. This leads to a suitable device being automatically set up to use a driverless backend driver when it is connected to a USB port. The above is all new info to me, but the default driverless install is a 7 letter disaster. synaptic says its (ipp-usb) installed, but its not running. And the printer is plugged into both usb3 AND cat5. And was for all 7 installs. Can we sort one problem at a time? I'd feel blessed if I only had 1 problem, but bullseye has so many I've no clue where to start. All the very best, as ever, Andy Cater Thanks Andy. Cheers, Gene.
