Summary: I'm using this multifunction device in a home office with a MacBook Pro and an HP laptop. I have always used Canons because they have a long relationship with Apple, and I have used Apple products since the 1980s.
Pros: Small footprint. Very satisfied with ease of installation. In the past, I had always hooked my printers up with a USB cable. I was amazed and very pleased with the simplicity and accurateness of the instructions for a wireless install. I am plus 70 senior and I was able to install without hitch.
Summary: I had Canon MF4270 failed recently and MF4890dw is definitely a great upgrade. No issue unpacking, easy installation, more functions, duplex printing, scanning and copying. The only problem is the starter cartridge low, which get warning on the first print.
Conclusion: My last printer was a Canon inkjet which still runs fine after 6 years. But it gradually dawned on me that a laser would have lower operating costs, and other advantages. I wanted another Canon, and was able to get this one at a killer price. It prints much faster than my old printer.
Conclusion: 4-in-1 desktop laser unit top rated in 2015 CR Buying Guide.....New printer in sealed box came without any literature, software, or warranty paperwork. That said waiting on Big Box chain supplier to either replace this obviously used printer or supply needed info. That said..
Summary: Very poor software. Scan quality is acceptable only for text. Scan time is somewhat slow. Print quality is OK. Copy quality is OK. Didn't try the fax function. I tried this device on my Windows 8.1 machine and Ubuntu 14.04 machine. The software utility looks like it was written in 1998.
