OKI B721dn in More Detail

Double Sided Printing with Speed

The Oki B721dn A4 mono laser printer has double-sided printing and network connectivity as standard. 

It has been designed for high volume printing environments and has a duty cycle of 200,000 prints and a typical monthly print volume of up to 30,000 prints.

Expandable Paper Capacity to suit your needs

This printer has a standard paper tray of 530 sheets and a 100 sheet multi-purpose tray.

Further additions can be made to the setup of the printer by adding up to 3 additional 530 sheet trays or a 2,000 sheet high capacity feeder. 

Maximum paper capacity for this machine is 3,160 sheets.

Fast Printing

A fast print speed of 47 pages per minute means it can handle the most time demanding print jobs as well as having the additional quality of a laser printer.

This printer will be attractive for business and industries that have a lot of transactional printing such as shipping documents and policy documents. Therefore this is an ideal choice for insurance and shipping companies.

User intervention is also kept to a minimum as there is only one single consumable that needs changing when it runs out.

Lower your Costs

Your operating costs can be lowered with this machine as it only has one consumable which is the print cartridge (toner/drum unit) that only needs changing every 18,000 pages. 

A separate maintenance kit only needs replacing after every 200,000 prints and it includes a new fuser unit and rollers

The printer ships with a 10,000 page print cartridge.

Customer Questions & Answers

Can't find the answer you're looking for? Our printer experts are here to help! Ask a Question
  • I'm looking for a strong reliable laser printer for label printing. It needs to have as straight a paper path through the printer as possible with large paper tray and not using the MP feeder on the front.I can't tell if this printer can do this or if the paper path if more S shaped. The reason this is an issue is our current label printer can gum up or peel inside. Any advice is appreciated. Cheers Chris

    For advice on the perfect label printer, please call our sales team on 0800 840 1992 and they will be able to advise you on the best label printer for you.

    I found it very difficult to select a printer to meet my requirements from the wide range available. The Printerland salesman was very knowledgeable and was able to guide me to the product that was right for my needs. Printer arrived next working day and exceeds my expectations.

What is AirPrint?

Apple AirPrint allows full colour, top-quality printing from iOS devices such as iPhones and iPads directly from within many Apps available from the Apple App Store.

To take advantage of AirPrint, your compatible printer must be connected to the same wireless network as your iOS device or Mac computer.

AirPrint enables users to print wirelessly from within applications on Apple devices to AirPrint Compatible Printers connected to a wireless network. You can use your iPhone, iPod Touch or iPad to easily print via Airprint without the need to install drivers or configure the printer queue. Just tap 'print' and select your AirPrint compatible printer, and print!....It's that simple.

What You See is What You Print

If you can open it on your apple device, chances are you can print it with AirPrint and an AirPrint compatible printer. Airprint works with Safari, Mail, Photos, iWork, PDF's in iBooks and many third-party AirPrint compatible apps available from the app store.

Full list of AirPrint compatible printers

Third-Party Apps

There are also a wide variety of third-party apps available to enable wireless printing through Apple devices, even to machines that are not natively AirPrint compatible printers. By sharing a printer installed on an Apple Mac or Windows Pc over a wireless network any printer may be able to take advantage of the AirPrint features. (An additional third-party app may be required to be installed on the local machine)

*For full AirPrint support, a printer firmware upgrade may be required which is available directly from the relevant manufacturer website.

Please note. Whilst every effort has been made to ensure that the above information is correct at the time of publication, Printerland will not be held responsible for the content of any third-party software suggested on this site and usage of any such software is at the users own risk.
