Have no complaints whatsoever about quality. BUT I will do everything I can to hack your HP 30X (CF230X) High Yield Black Original LaserJet Toner Cartridge and refill the toner myself. The waste generated from one time use Cartridge is CRIMINAL. It disgusts me how your greedy company does not care about such rabid waste. Disgusting, trash the planet for more profit.Your cartridge should be refillable!!!
When my printer tells me that I my toner is very low, I order a 30X cartridge knowing that it will last a very long time. Usually I can guarantee that the "very low" cartridge still has 3 months of use left in it and I just keep using it until the print quality is also "very low". So, don't be fooled by what your printer tells you!
