high delay between pages when printing

[colttt]

Describe the bug
We have a Debian based print server running, all printers are connected via IPP but it takes a while if it starts printing and then for each page it tooks >15s for the next page.

To Reproduce
Steps to reproduce the behavior:

1. add printer HP Pagewide Pro MFP 477dw via IPP to your print server
2. try to print some pages, the OS (Linux, Windows, MacOS) doesn't matter, also the format (plain text or PDF)

Expected behavior
fast printing which happens immediately

Screenshots

System Information:

• OS: Debian 12 (bookworm)
• cups-version: 2.4.2-3+deb12u1

I attach the error_log with debug information with just one print job of 10pages, I also attach the ppd file for this printer
AEI-IT-103.ppd.txt
error_log.txt

according to the Documentation I tried ?waitjob=false&waitprinter=false at the end of the deviceURI and restart cups, but it's still the same

I tested it with cups 2.3.3.op2 from Debian 11 (bullseye), with the same configuration it works fine and fast.
I also looked into the printer.config and ppd file of these two versions, and they are similar (expect some minor things), so I still think here is something wrong wit cups!?
