Looks like an idea worth examining. Let's look at what's on the tin and inside it. Accordin to https://mopria.org/certified-products#company30 my ENVY 4502 is a Mopria-certified product. It is on a managed WiFi network Part of its TXT record shows: pdl=application/vnd.hp-PCL,image/jpeg,application/PCLm,image/urf application/PCLm is acceptable to a Mopria. (I think it is meant to used with Wi-Fi Direct and not a managed WiFi network, but we'll put that on one side because a more pressing issue is about to emerge). CUPS will give the printer destination with brian@desktop:~$ lpstat -e ENVY4500 and generate a PPD with brian@desktop:~$ lpoptions -p ENVY4500 -l Examine the PPD with brian@desktop:~# grep "cupsFilter2" /etc/cups/ppd/ENVY4500.ppd *cupsFilter2: "image/jpeg image/jpeg 0 -" *cupsFilter2: "image/urf image/urf 100 -" CUPS will only process jpeg and Apple raster (AirPrint). The filtering system *must* send either of these two MIME types for printing to take place. Having Mopria on the box isn't any indication that Driverless Printing is possible with this printer. A much better indication is looking for AirPrint-capabilty. CUPS will accept and process image/urf. All modern printers have an AirPrint service that is known to work splenedidly with the Debian printing system. -- Brian.
