What I was looking for:
- Low cost per page for infrequent use - mostly BW. Speed is not critical.
- Multi-Function Printer (MFP) i.e. printing and scanning, preferably with Automatic Document Feeder (ADF), I don't care about FAX
- Wireless connection
- Easy menu operations - preferable with some not that minimalistic screen
- Scan to USB - this one I find very handy
- Duplex printing - desirable
