Thanks for pointing that out. The non-commercial license is a disappointment, but it's still better than conventional printers.

This is one of the first appliances I tought about when I discovered open hardware. Considering it was a proprietary printer that first roused Richard Stallman's anger, and considering printers have had some of the most unfair and obnoxious defective designs, it seemed only fitting to liberate those machines first. Only a few weeks ago did I have a friend telling me their printer had refused to work, until pers figured out pers's subscription had expired. There was nothing I could do apart from warning them once more about DRM and proprietary software and hardware. It is good news indeed to see someone working on this.
