Has anyone attempted to interface a HP82240A "Redeye" printer to an Arduino? I have several of these printers and would like to use them to do data logging for a project I am working on.
I have plenty of documentation on the printers and the printing protocols (which I will share) but lack the expertise to implement an interface (serial to IR???)
Any enlightenment will be appreciated!

At the lowest level, serial-to-IR is handled by hardware modules that are kinda like "IR modems" (really old-fashioned dumb modems, not like Hayes modems with a built-in micro).
But, just as you can layer TCP/IP on top of Ethernet or serial, it's possible to layer a lot of protocol on top of a simple IrDA serial bitstream. So, the important question is how complex a protocol those printers require. It's probably not much, since they were designed to work with very simple calculators.
There are, almost certainly, some examples of projects people have already done to interface simple micros to those printers (or, at least, to ones similar to them). Have you done a google search for something that might be adaptable to the Arduino?
