YINGHUA Printhead Ink Supply Station for HP T790

Compatible Printhead for HP T790

This printhead is designed as a direct replacement for the HP T790 large-format printer. It serves print shops and technical-document teams that need consistent output without switching to OEM-only supplies. The part installs in the existing carriage and restores the ink-delivery path when the original unit reaches end of life.

Replaces worn original printhead

The station replaces the factory printhead when nozzle clogging or electrical failure degrades line quality. Swapping it restores sharp lines and solid fills without requiring a full printer swap. The jump is worth it when cleaning cycles no longer recover missing nozzles and downtime costs exceed the part cost.

Steady output during long runs

Under sustained printing the station maintains uniform ink flow across all channels, preventing banding on extended plots and posters. Thermal behaviour stays stable so droplet placement remains accurate from the first page to the last. It is not for users who need integrated ink tanks or a different ink chemistry.
