Comment Canon MX870 (Score 1) 190
If you really must go the route of keeping the Chromebook, I would suggest the Canon MX 3/4 in one printers. I myself have an MX870 model (printer/fax/copier/scanner), it's WIFI, and it has a USB port, an SD port, a compact flash port and an MS Duo port. From a USB stick I've printed PDFs, DOCs, text files, jpegs without a problem. I've also printed jpegs right off an SD card. It also works in the other direction; I've scanned some docs/images and saved them directly onto a USB stick.
