One million trees just died. The problem with some of the earlier HP printers was that they would accept unsigned firmware updates, you could literally reflash the thing with an update instruction in postscript.

Some work was done at Columbia University with developing trojanised firmware, i recall a firmware that could transmit CC# over tcp when it saw then in the print stream.

Extreme care must be taken if connecting printers to the Internet. It's at best a horrible idea and I'd say that most of these are unknown to their owners. Hopefully this gets some MSM coverage and people address the connected printer problem forever. (not likely)
