I simply times the complete toner set with all cartridges for my HP LaserJet Pro 200 M276nw e-All-in-One color laser multifunction printer with ink service to try out - ordered Printer Consumables. Surprised by the really good Print results overall I ordered end September 2014 again a black toner cartridge. This began in the left margin to print gray dots, what the overall picture rather disturbed just in business correspondence a few days ago on everything you print. The level of the toner was still at about 80%. In my Written Question I got very short of good quality advice and tips to the errors to eliminate. Even a replacement the cartridge was offered to me without any problems. Personally, I am enthusiastic about the customer friendliness and service and may I now also among the regulars. Cheap prices with very good service, I praise and has unfortunately become very rare!
