Trying to print but this message appears

Getting “pdftops-renderer (see cups-filters README FILE) to use Ghostscript or Mu pdf for the PDF → Postscript conversion.” message
Im using a laserjet 1018 running kde plasma 5.15.28-1 it printed just fine up until today for some reason. I am running HP LaserJet 1018 Foomatic/foo2zjs-z1 as printer driver

Might be related to this CUPS/Troubleshooting - ArchWiki

So, by running:

sudo lpadmin -p printer -o pdftops-renderer-default=pdftops

should be fixed, or see the next troubleshoot part of the wiki …

it didnt work it says the page is printed even tho it wasnt

Maybe uninstall hplip
Reinstall foo2zjs i guess you installed the foo2zjs-nightly from AUR, but before that, maybe you also will install first the foomatic-db package because by default there is only the foomatic-db-engine
