My HP LaserJet has been telling me that it is low for the better part of 10 years. Still prints fine.

It's hard to really judge what this means without knowing how often and much you print, as well as how much was printed before the warning was given.

PS

Blame/thank Canon. It's their mechanism and cartridge in the HP printers. Also some utilize Samsung print engines for A3 paper.

It's a testament to ink vs toner that it can remain functional after 10 years.
