HP supports mobile printing (on devices like phones and tablets) with a number of free apps. The two most important ones are HP Eprint App (E-App) and the HP All In One Remote app (AIO app). These apps are available (for free) from the appStore (in the Apple world [figure]) and the playStore (in the Google world).

The E-App focuses on navigating to media and then printing it.

The AIO-App is more sophisticated and provides for scanning or camera-capture of documents or images along with processing to common image (jpeg) or document (pdf) file formats. These files can also be printed. They are saved in local files such as 2013-11-27:14:35.pdf and can be printed or forward via email. (fig. 12,13,14)

Typically the apps must be activated the first time they are run. This involves entering the HPC account name and printer email address. The system does a security cheque and provides a 4 digit activation code (by email behind the scenes) to complete the setup. (fig. 15 activation)

The layout (or user interface ) for the apps various depending on the platform (ipad, iphone, android phone or tablet) and version of the software. Separate sections are presented in the links on the index page (at left) for different platforms. General instruction for use are given below.

The apps can print (or communicate) using 3 communication methods.

  1. airprint (auto discovery) requires the the phone or tablet be connected to the same wi-fi network as the printer and be in range of the router. The Apple ios operating system has airprint software built in as do more and more android tablets. Airprint is activated using the action icon: and then selecting 'print'. (fig. 15) Airprint software works without having to install any HP app.
  2. the eprint system using the printers standard wireless network connection at a fixed IP address. An eprint is a more fool proof connection since the printer can be reached either using the wi-fi system or the cellular system (when out of range of the router). Eprint requires following a setup procedure (detailed elsewhere) that results in an email address for your printer like: myPrinter@hpeprint.com The user simply emails whatever he wants printed to his printer and it prints it when received. In the background special hp cloud servers analyse, format, and forward the document for printing to the customers specific type of printer. No print drivers are required. Conventional pc software install is not necessary.
  3. the printers wl-direct antenna (if so equiped) can create a network eg. hp-xx-envy5530 network ( meant to be temporary in nature). Users switch their device to this network to print. After printing, users must switch back to their main wi-fi network in order for all other programs to work on the internet.

The apps also provide links to adjust printer settings (paper type and size), get ink levels (cyan, magenta, yellow, black) and perform print reports (alignment, network etc). (fig.
