Why does a CUPS shared printer by HP doesn't print as expected?

[ValeraOfgap]

I want to set up a shared printer with HP LaserJet Pro MFP M28a and Raspberry Pi OS via the CUPS sharing feature.

The printer is set up as IPP Everywhere and it prints via lp command (in the Rasp. Pi), but can't via a web UI: it cancels the job (given state is "Print job canceled at printer."). Also, the printer can't print via a remote host (CUPS (2.4.14), Linux manjaro 6.16.8-1-MANJARO #1 SMP PREEMPT_DYNAMIC Fri, 19 Sep 2025 16:09:36 +0000 x86_64 GNU/Linux), where I added that shared printer, its connection is dnssd://HP%20LaserJet%20Pro%20MFP%20M28a%20%40%20raspberrypi._ipp._tcp.local/cups?uuid=f5824a6f-023f-3dc2-7703-7aca0a8a45bc. The reason for it is the same (canceled at the printer).

Printing works fine in Android 15 @ OPPO A78 via Default Print Service, which finds the printer and prints jobs without any issues.

What may a problem be?

Here is CUPS log of the Rasp (debug mode) after a print attempt:
