Have the toner on Bubprint ordered because I have the dealer compatible cartridges for my Brother inkjet in use that have been easily done their services. I thought to myself, what is closer and at this dealer to order the extremely low toner for my Mono Laser Printer HL-2250 DN. After the original starter kit was used up, I only compatible toner used in the printer and is currently the second toner cartridge from Bubprint already in use. I have about 8900 pages printed by the printer. The toner was installed as described and used. There were previously never had problems with the detection of the toner cartridge. I print to the printer mainly brochures, has been able to detect any significant differences from the original, and I am completely satisfied with the print quality of compatible toner. As always, I am once again thrilled by the fast delivery and good packaging of the products.
