While I asked a similar question to the moderator forum.

A couple nods to the monster Canon mx870 (look at the pounds!) I think folk that do envelopes are going to be picky. This unit has 2 years on it and it uses ink just like all printers do. I can't say it's any worse or better.

It does work well over WiFi and scans to memory cards and sticks. I never tried the network scan feature.
