HP ePrint via email is a feature included in select HP printer models that allows you to print documents or photos by emailing them directly to the web-connected HP printer. No printer driver or app is necessary. Simply email the documents from the device (laptop, tablet, smart phone, or other email-capable device) to an email address assigned to the printer.
This document explains what is required and how to print with HP ePrint via email.
