Would it be possible to "expand" a regular household printer? Answered
Basically, what i'm talking about is taking apart a normal A4 printer and expading the paper feed and guide rails so it can accomodate paper of any size. The purely mechanical aspect certainly seems doable, although you'd run out of ink a lot faster, and I have no idea how to tackle the software issues.
It seems theoretically possible, but i'm not sure about how you'd actually go about it - tips/help and any links would be appreciated.
