I’ve always stuck with HP cartridges for our HP printer for two big reasons. At two places I’ve worked, as well as some people I know, ended up having problems with a printer after using off brand cartridges, and the manufacturer wouldn’t help when a problem arose because it was caused by an unauthorized cartridge. And at another former job, the owner bought an off brand cartridge, and the documents did not print as well. So I’m risk adverse about off brand, and we do sometimes have to send out documents we’ve printed. But if other people can recommend a good off brand source it could be worth a try.
