![]() Especially there is a new approach for IPP-over-USB implementation which solves most of ippusbxd’s problems. Also did some debugging on ippusbxd with he authors of the SANE backends and found out about the shortcomings of ippusbxd’s architecture. ippusbxd: ippusbxd does not only do IPP printing via USB, it also gives access to non-IPP HTTP services, as the web admin interface of the printer and even scanning, using AirPrint/eSCL with the new SANE backends.Note that this is not PWG’s IPP Scan standard. This will enable scanning on most modern printer/scanner multi-function devices and also allows USB scanning via ippusbxd. Did many tests for the authors to debug the backends so that my HP DeskJet 2540 and my HP OfficeJet Pro 8730 scan this way. ![]() driverless (or standard-based?) scanning: Tested new SANE backends (“ airscan” and “escl”) for scanning on multi-function devices which do Apple AirPrint, as they then also do Apple AirScan.cups-filters: Released 1.26.2 to make the cups-browsed work with CUPS running on others than the standard port 631, needed for the snap.cups-filters: Released 1.26.1 to make the cups-browsed-generated local print queues actually work on all OS distributions and to get legacy (not actually designed for driverless IPP) printers better working.printing-stack-snap: Updated to CUPS 2.3.1, cups-filters 1.26.2, QPDF 9.1.0, added Ghostscript 9.50 as default PDF renderer (for better output quality and to also accept PostScript input), made all building again with current snapcraft, several configuration improvements, debugging options (see last commits). ![]()
