OKI Mobile Printing
OKI & Mobile Printing
With the modern mobile workforce increasing at a rapid rate, and the growing popularity of tablets, smartphones and laptops, printing documents where and when you need them adds a whole new meaning to print on demand providing you have access to a compatible device.
Thanks to the many mobile applications available, you no longer have to be ‘back in the office’ to print and share documents essential to your business, customers or partners; promotional customer information, contracts - you can keep your business going whilst you are on the move.
Printing from Apple iPad or iPhone?
How to print to an OKI Printer from an Apple iPad
How does mobile printing work?
Cloud or mobile printing works by connecting to a wireless, networked or web enabled printer through a smartphone device or tablet, meaning you can print remotely from anywhere in the world, without having to connect directly to a printer nearby.
OKI products & Mobile Printing
OKI Colour, mono and multifunction printers are compatible with a number of applications available, so you can download an application of your choice that enables you to print to almost any device simply through a single mobile printing application.
Microtech Corp’s ePrint and Cortado Workplace, for example, are compatible with most printer manufacturer brands including OKI’s portfolio of mono and colour LED printers and MFPs.
Microtech Corp's website - compatible with iOS and Android devices*
Cortado's website - compatible with iOS, Blackberry, Android and Symbian devices*
*please note: a PC or Apple Mac on the same wireless network may be required for full compatibility.

OKI® Print Job Accounting software enables you to securely monitor your print fleet so you can charge back departments, bill back clients, and control the cost of colour prints.
See Exactly Who is Printing What
This optional application for OKI colour, mono and multifunction printers helps to give you a clear overview of of print activity by tracking the output of each individual user or department.
