I am new to Linux and i am using Ubuntu. I have downloaded wps office BUT i cannot print to my hp laserjet printer. please help

First go to settings, devices and add printer. If you see yours add it as default option and then try again print. If it won't work try to install drivers for your printer.

Very interesting, what looks to be pixels fading is actually the other way around. Great way to tell who is part of the circle and who isn't.
