I've installed, deleted, reinstalled the app and and the printer for the HP 4100 series and it will not print my document.
Tried switching computer / phone etc on and off. It printed one page from my phone earlier but has refused to do it again since! Please help!
MacBook Air 13″, macOS 14.0
I suggest starting by visiting HP Support, for this specific printer here:
https://support.hp.com/us-en/product/troubleshooting/hp-deskjet-plus-4100-all-in-one-series/29378221
In addition, the HP printer supports AirPrint. Have you tried printing from your iPhone, via AirPrint, instead of via the HP Smart app?
