HP ePrint was a term used by Hewlett-Packard to describe a variety of printing technologies developed for mobile computing devices, such as smartphones, tablet computers, and laptops.

HP discontinued ePrint on models released after fall of 2020.

Many HP ePrint technologies use cloud resources to provide mobile printing capabilities for specific HP ePrint-enabled printers and MFPs and for other printers using applications that provide network printing. The HP ePrint portfolio includes the following:

HP ePrint via Email is a feature that most HP printers and MFPs use. HP ePrint enables printing documents attached to email messages sent to the device. The HP ePrint-capable printer or MFP must be registered to an HP ePrint cloud service called HP ePrint Center, which assigns a unique email address to the printer or MFP. The assigned email address is customizable but by default is arbitrarily set to promote security since only those who know the email address can use it to print. HP ePrint via Email does not require a print driver installed on the client. The HP ePrint public cloud renders the printing data from each separate attachment into a suitable print data stream, such as PCL3, PCL 5, or PostScript, and, subsequently, sends it to the HP ePrint-enabled printer. For this to work, the attachments for printing must be in a native plain format, such as any of the following:

Any email-capable client, including a smartphone, a tablet computer, a laptop, or any other email client, can submit print jobs to HP ePrint via email. Registered users can also log into the HP ePrint Centre to manage and view their print jobs, printers, and settings. For example, HP ePrint Centre provides options to create lists of users approved to print, and it includes spam filters to prevent unwanted print requests. Users can also change the email address of the HP ePrint-enabled printer or MFP by requesting a new one (each HP ePrint email address must be unique and thus, must be approved). Figure 1 shows how data flows from the email client to the HP ePrint public cloud server (HP ePrint Centre) for rendering into an acceptable print stream format and then forwarded to the HP ePrint-enabled printer or MFP.

HP ePrint Public Print Locations is a mobile printing service that prints from the cloud using one of the HP ePrint mobile device apps. HP ePrint Public Print Locations is meant for people who use printers while travelling. It also enables a business or a public facility to charge for printing. For example, a businessperson preparing for a presentation can print handouts at a destination hotel for a fee rather than carrying them as they travel, or a traveller can print a boarding pass at a hotel to save waiting in line at the airport.

The HP ePrint apps are free and include versions for Apple iPhones and Android devices. Users can find it at the iTunes App Store or Google Play. It is also available for Blackberry mobile devices from BlackBerry App World. The HP ePrint app lists various registered HP ePrint public printers at locations, such as hotels, airports, and print shops.

When a user submits a print job to HP ePrint Public Print Locations, the service returns a notification email message with an authorisation code that is required for printing at the device. This authorisation code prevents unwanted printing and depending on the business model enables the owner of the printer to charge for printing before the documents are printed.
