why I can't install my HP photosmart D110 in my Mcbook air?

Hi,

You do not mention the operating system version in use.

Have you tried the HP 5.1.1 Printer Software Update from Apple? An HP Photosmart D110 series version 3.3.2 driver is listed in Printer and scanner drivers for Mac - Apple Support. However, it should be noted that the System Requirements for the HP 5.1.1 Printer Software Update say Not compatible with macOS v12 and newer, but at least one report (about an HP LaserJet P1005) indicated successful use even with macOS 12.1. You may have to look upon this as an experiment. Make sure that backup copies have been made of all important files (documents, photos, et cetera) before testing anything.

Reset the printing system on your Mac to solve a problem – Apple Support (UK)
