Rocky 9.1 After last upgrading, the printer won't work

I looked for the firmware files (those with the .fw extension) and found the situation, which I display in the firmware.txt file. I did the same with Ubuntu, then with Linux Mint, and the results are identical. The difference is that, while the printer works on the two distributions, it refuses to work on Rocky. I used the command $sudo find / -type f -name 'laser.fw’ cat > /home/omarian/firmware.txt* and I got the text file that is identical for all linux distributions which I have.


I also looked for firmware for foo2zjs and did not find it, instead, I found some .ppd files, including for my printer, HP LaserJet 1020. They were located in /etc/cups/ppd. I assumed that this is what I should be looking for, firmware to load at boot, but if it is wrong and I should be looking for something else, then I think I should receive additional indications for which I thank you gratefully.
