  • Jennie Bayliss 22 June 2016 4.75 / 5 Value 5 Features 4 Quality 5 Performance 5 So good I bought a 2nd one!

    This is the 2nd OKI C321DN printer I have bought. I like the quality of the print. I like there are 3 levels to save toner when printing - the middle option is more than good enough for internal documents. I like the ease of changing toners - fast and easy to do. The only slight downside is the cost of the toners - but as the volume of print is low for me, the quality is what matters the most.

  • Colin King 24 March 2016 5 / 5 Value 5 Features 5 Quality 5 Performance 5 Good, all round printer

    Mainly use for graphics design work. Excellent print quality at a good speed. Straight through feed for heavy card very useful. A good choice of printer.

  • Vikram Dhawan 01 April 2014 5 / 5 Value 5 Features 5 Quality 5 Performance 5 User Review

    This is a great little printer for home or office. The print quality is very good. It includes network and double sided printing as standard. You can print labels and envelopes. Software for this is included on a CD. The downside is that the supplied toner covers only 750 sheets at 5% in colour and black. You will have to fork out a lot more for the standard 2k sheet toner. You can't refill the initial set either, only the replacement cartriges when they empty. I had the C5450 and it lasted over 5 years. It's still working but the cost of replacing toner is high so I chose to replace it with this one.

  • Bernard Froe 12 February 2014 5 / 5 Value 5 Features 5 Quality 5 Performance 5 Printer

    Reasonbly quiet printer print speed very good have had to replace toner black and cyan good choice of toner price and you can get larger capacity ones. Brilliant colour printing even on white standard paper easy to setup even on an imac.
