net-print/cups-filters-1.28.17-r1: Libreoffice ignores duplex when Printer language type is set to PDF #520

Hi, Im not sure whether this is a bug or some misconfiguration. Although I have Duplex=on settings in Libreoffice and even in cups I set default settings for my "HP OfficeJet Pro 7740 Wide Format All In One" (firmware version EDWINXPP1N002.2246A.00) printer to enabled it still prints pages one-sided (single-sided). The driver is HP Officejet Pro 7740 Series, hpcups 3.22.10.

I can work around that by setting Printer language type to Postscript Level 2 or Postscript Level 3.

I can also Export from Libreoffice to PDF file and then print it using lpr (it comes out double-sided as expected).

I am on Gentoo Linux and I see cups-filters I recently recompiled without PDF support (postscript was left enabled) due to issues with dependency on mupdf. The cups package was compiled with pdf and postscript options, so only the filters were "missing" some pdf-related stuff. But provided lpr can print double-sided PDF file I assume this is a Libreoffice bug:

Version: 7.4.6.2 / LibreOffice Community
Build ID: 40(Build:2)
CPU threads: 4; OS: Linux 6.1; UI render: default; VCL: gtk3
Locale: cs-CZ (cs_CZ.UTF-8); UI: en-US
Gentoo official package
Calc: threaded

I cannot find at https://www.cups.org/documentation.html an installation manual to check what the supposedly configure --enable-pdf flag really does. Even if I knew I am not certain why Libreoffice can speak to the printer in PDF while just the duplex=on is ignored. Could cups return a message to Libreoffice stating the selected Printer lanuguage type is wrong? Like Libreoffice parsing some output from some cups utility describing the capabilities?

Meanwhile I recompiled/reinstalled cups-filters with the "pdf" support and restarted cupsd and still printing from Libreoffice results in one-sided printouts. Possibly I am not the only one to hit this: https://ask.libreoffice.org/t/writer-will-not-print-duplex-2-sided-pages-despite-proper-printer-setting-and-lo-print-setting/70152/4

The only "errors" I see in /var/log/cups/access_log are: 

E [08/Apr/2023:16:58:42 +0200] Unknown directive IdleExitTimeout on line 12 of /etc/cups/cupsd.conf.

I think the logs could include at least a communication protocol language and a number of pages, by default.

I ran the cupsctl --debug-logging and have the /var/log/cups/error_log ready for someone here error_log.txt

From error_log.txt:

[Job 377] argv[5]="Duplex=None...

Doesn't look like a CUPS or cups-filters issue to me.
