LD Products HP 42A Q5942A Black Toner 2-Pack

This LD Products two-pack supplies 10000 pages per cartridge for HP LaserJet 4240, 4250 and 4350 series printers. It is a compatible replacement for the HP 42A Q5942A black toner. The dye-based formulation is built for offices that print high volumes of text documents. Buyers who need colour output or inkjet compatibility should look elsewhere.

Sustained office printing

Each cartridge is rated at 10000 pages under the ISO/IEC 5% coverage standard, so yield remains predictable across long print runs. The remanufactured units undergo a testing process that monitors density and reliability over successive jobs. Consistent output reduces the frequency of cartridge swaps during heavy workload periods. Printers purchased outside the United States and Canada are not supported.

Remanufactured build and fit

Cartridges arrive as a matched pair in retail packaging that may vary by lot. The mechanical interface matches the original HP 42A specification, allowing direct installation in the listed LaserJet models. Using compatible toner does not void the printer warranty. Shops that require OEM-branded consumables or region-free operation will need a different product.
