I have a Brother B&W laser printer..2 actually. The first one was a 100 dollar one Black Friday 6 years ago. Running out of ink?...bought another same model Black Friday 80 dollars...friend gave me a cartridge about 5 days later. Installed in the old one...back to square one but prints just slightly lighter. Probably a software fix but it works ok. Kept the new one JIC. I print invoices targets shipping labels etc. No ink drying out. I don't need to print colors.
