1Introduction

The emergence of mobile devices and cloud services has revolutionized business productivity and innovation.
However, even the best-equipped mobile employees find themselves hunting down places to print (and get
printing assistance) while on the go.

HP ePrint Enterprise is a server-based mobile printing solution that makes it easy for employees to print
from mobile devices to any registered printer on enterprise network, while keeping data safely within the
company network. This solution makes it simple to convert mobile content (such as Word documents,
images, PDFs, etc.), into hard copy for easy reading, markup, and sharing while on the go.

The solution is easy to manage, scalable, and secure; preserves administrator control even in a BYOD
environment; and allows options for mobile device management (MDM) integration.

1.1 Solution at a glance

Flexible integration

Device-to-printer connections and print job processing are managed by the server software rather than
individual print drivers. As a result, HP ePrint Enterprise integrates seamlessly into existing infrastructure,
supporting both HP and non-HP printers.

Enhanced data security and control

HP ePrint Enterprise helps to preserve security controls without compromising your employees’ productivity.
The HP ePrint Enterprise for Good, MobileIron, and BlackBerry 10 apps place corporate data in a secure
container—preventing contact with the open Internet and personal apps.

IT managers can use the HP ePrint Enterprise software to control who can print, and where—such as
restricting access to a dedicated printer for employees in a specific role. All job control data passes through
the HP ePrint Enterprise server software, making it easy for IT to collect and analyze. For additional
flexibility, the touch-to-authenticate feature enables mobile users to authenticate and release jobs using a
near field communication (NFC)-enabled smartphone or tablet.

Easy mobile printing from any device

Employees can print documents from any email-capable device; from the HP ePrint Enterprise app for
Android, iOS, or BlackBerry; and from the HP ePrint Mobile Driver for laptops and tablets.

2 Printing to HP ePrint Enterprise

The versatility of HP ePrint Enterprise allows IT department to choose several ways to enable cloud-based
mobile printing. Depending on the organization’s needs, IT department can implement app-based printing,
email-based printing, or both. With HP ePrint Enterprise, truly mobile printing is now a reality.

2.1 Using email clients

Every printer added to the server via HP ePrint Enterprise admin console will have a unique email address
assigned for it. With the simple email-to-print capability, users can send a print job from a corporate email
address to network printers that have been assigned an email address.

To achieve the email printing, exchange server on the corporate environment should have a mechanism to
route the emails intended to reach HP ePrint Enterprise Server (printer email accounts) so that it can process
the job and send it to the appropriate printer for printing.

The following figure represents a high-level overview of email-to-print workflow:

2.2 Using mobile apps

HP ePrint Enterprise Mobile apps must be downloaded and installed on mobile devices. These applications
access three services provided by HP ePrint Enterprise server, for which Mobile apps must be able to
establish an HTTP/S connection with HP ePrint Enterprise server.

1. Printer searching (via HTTP/S

2. Job submission request (via HTTP/S), and

3. Content transfer (through email via SMTP, or content upload via HTTP/S)

2 Chapter 2 Printing to HP ePrint Enterprise

Additionally, corporate email server must be able to address the HP ePrint Enterprise SMTP if content is
transferred through email.

Following figure represents a high-level overview of mobile apps print workflow:

Scenario 1 — HTTP/S is the only communication protocol for all three operations. Though this seems like an
easier setup, there is a drawback: printing any email content requires downloading and uploading the
content back to the corporate network. If a regular mobile data connection (e.g. 3G) is being used, this means
a lot of data transfer.

Scenario 2 — Typically the case for BlackBerry clients (running OS 7 and below), this scenario provides an
easier method for transferring email content: simple, in-house email forward is not only cheaper (no heavy
data transfer), but safer (the content never leaves the boundaries of corporate network).

2.2.1 Enterprise connectivity

For Android, iPhone, and BlackBerry (OS 10 and above) devices, the enterprise network infrastructure will
have to provide clients with means to connect with HP ePrint Enterprise Server over VPN, Local Wi-Fi or an
equivalent.

The following figure represents a high-level overview of enterprise connectivity over VPN:
