fedora 38: grainy printing with hp lj pro mfp m130fw

[Gianluca Cecchi <gianluca.cecchi@xxxxxxxxx>]

Hello,

after upgrading from fedora 37 to 38 the scanner still works quite well, but it seems that my printing is somehow grainy, even for well defined documents.

Initially I thought of a possible reason with the just replaced toner but then trying to print the same pdf file from my Samsung S22 phone it prints perfectly.

Both the printer and the phone use wifi connection.

After upgrading I got the usual message that the driver needed to be reinstalled but I continually got checksum error and it didn't complete.

I then manually downloaded from here:

https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/

and gave the .run file to the wizard as input and the printer worked again, but output is grainy.

On my fedora 38 I have hplip-3.23.5-8.fc38.x86_64 so I downloaded the hplip-3.23.5-plugin.run file from the web site above.

Could that be the reason?

Running hp-check I see

Any other better optimized ppd to use? Or anything else to check/debug?
