Installed Manjaro ~ 2 months ago and printing worked.
Have done updates occasionally on work and home machine (each has an HP Office jetPro 8600 Plus printer), but for both printing has slowed. After the most recent update last week my home machine printing processes jobs a very long time... and does not print, while our home Xubuntu laptop prints to the printer just fine. The system also seemed to drop the printer settings from enabled, which I have reset without solution. Reboot does not help.
Not being able to print again is a big deal.
