Brother monochrome laserjet. Lasts forever. Documents requiring a signature, school materials (homeschooled), shipping labels, documents to annotate to be scanned in and sent off, etc.

After a few runs to a FedEx Office where you can send a document to be retrieved and printed with a code at a terminal attached to a copier, considering the value of time and the cost of those prints per pages, ~$125 is a no brainer for something that will last 5-10 years at least. Comes out to $20-$30/year with some supplies in there (paper, toner).
