The toner is very expensive and there is no incentive for returning used cartridges. The process for receiving "free" shipping is somewhat deceptive, as a third party is involved that asks for a monthly fee for the privilege of "free" shipping. The cartridges do arrive quickly and are easy to install. The print quality is good.
I purchased a printer and ordered the first replacement toner cartridges. I was shocked to find out they cost the same as a new printer. I guess I should just buy a new printer each time the toner runs out.
I noticed that the color on ,my HP was not what it once Wass and kept running calibrations and tests until my HP rep asked if I was using any less expensive generic toner....I checked and 2 of 4 were off label ...Cyan and yellow. I replaced them and now my printer is like brand new.
My printer has been screaming for toner for over a month--but still prints just fine. So, the new toner sits unopened for now. Appreciated the timely delivery.
