Printing and Speed: Prints color and black at 14 pages per minute, with excellent and clear color quality. Duplex Printing: Manual, meaning you flip the paper yourself from the settings if you want to print double-sided. Ink: Uses 4 ink cartridges model HP 131A (black, cyan, magenta, yellow). Black is sufficient for approximately 1,600 pages, and each color is sufficient for around 1,800 pages. Disclaimer: The printer is working perfectly without issues, but the print quality has lines and black dots on the pages. It likely needs a replacement of the black ink cartridge (as the drum is integrated with it) or internal cleaning. Reason for selling: I graduated.
