Default page size A4 not selected properly and duplex print failing

[Richard Lewis]

With HP OfficeJet 7740 Pro A3/A4 duplex printer the A4 page size is not selected properly and results in an incorrectly sized test page: "Media limits: 0.42 x 0.42 to 27.52 x 35.14 cm". In the printer set-up summary the media is described as "unknown" when A4 is selected as the default. If either A5 or A3 are selected, the media is described correctly in the summary - "iso_a5_148x210mm" or "iso_a3_297x420mm" - and the test pages print perfectly, with correct media limits shown.

When attempting to print A4 duplex the print fails due to a printer "jam", though printing the same document in duplex works properly using both the HP-Smart app on an Android phone and CUPS version 2.2.7-150000.3.51.2 on an OpenSuSE Leap 15.5 system. Therefore I think the "jam" is the printer thinking the paper should be larger than it is, expecting 35.66cm (35.14 + 0.42) when the A4 paper is of course only 29.7cm long.

On the OpenSuSE system the media is described correctly in the printer summary for the default A4 size paper.

I've looked at and compared PPD files in /etc/cups/ppd/ and cannot see anything amiss with the sizes mentioned for A4. I think the problem must lie in it assuming a size of 35.66cm when A4 is selected, i.e. it defaulting to "unknown" media, whatever that is.

I have the same issue on arch so most likely a cups issue. I reported a issue over there in case you want to add to it there: https://github.com/OpenPrinting/cups/issues/811
