Excellent – An excellent printer, the toner is easily purchased online at reasonable money. I haven't yet had to replace the drum. The printing operation is easy to understand, and double sided printing is a breeze. The back panel opens to allow printing of thicker cardboard, and single pages and envelopes can be loaded from the front. I've had this printer for around 4 years, and it has performed beautifully. The toner lasts for ages and is very cost effective. The error messages are a little confusing. I would have liked to see a list of error messages printed inside the printer.
