Szybko i tanio. Dzięki zniżce za kod oraz za ilość cena okazała się naprawdę atrakcyjna. Generalnie tusze są całkiem spoko, nigdy nie liczyłem dokładnie ich wydajności, natomiast uważam, że można je polecić.

Compatible Drum Unit 57A for HP (CF257A) (Black)
Manufacturer: DrTusz Manufacturer no: DT-BH-57A
Class: Drum Unit Type: Compatible Color: Black Dedicated to printers: Hewlett Packard
Compatible Drum Unit 57A for HP (CF257A) (Black) by DrTusz is the reliable choice when you want your HP LaserJet to keep producing sharp, clean text and consistent black printouts day after day.
Dear Customer, it’s worth remembering that a drum unit is not the same as a toner. Toner is the “ink powder”, while the drum is the precision imaging component that transfers it onto the page. When the drum is worn, even the best toner can’t deliver perfect results—so replacing it at the right moment restores clarity, smooth gradients and professional-looking documents.
This compatible 57A drum is designed to match the performance of the original, giving you the same dependable print quality and trouble-free operation, but in a smarter, budget-friendly way. With an impressive yield of up to 80,000 pages (at 5% coverage), it’s ideal for busy offices, schools and workgroups that print a lot and expect stable results without constant maintenance breaks.
We also encourage you to check the Related products tab—there you’ll find matching toners (including high-yield options) and original OEM alternatives, so you can easily complete your setup in one go. And as always, we carefully protect every parcel for safe transport.
