I am a newbie at both Ubuntu and troubleshooting printers.
I am using a HP Envy 4520 Printer hooked up through usb to Ubuntu 22.04.1 LTS
I looked but wasn't able to figure out the answer using: Can't find Ubuntu drivers for the HP Envy 4520 printer
First, the red ink ran out. After continuing to milk out that cartridge, I eventually replaced with a new color ink cartridge. However, then the cartridge only printed with colors EXCEPT Red. I could never get it to print red again.
Later, Black/Greyscale printouts are completely blank. So now, my printer only prints in blue and yellow.
I thought it was an issue with the cartridge so tried everything here including using hot water to try to dissolve any clot. https://www.minitool.com/news/hp-envy-4520-not-printing.html
I did the usual restart, clean cartridges, reset to defaults, etc.
So I believe that this bizarre behavior is due to a driver issue but have issues trying to fix this because I am more a windows user and just starting to use ubuntu.
Please advise. Thanks in advance.
