It might be worth considering LiMnO2 primary cells to power the heater. They have a higher energy density than LiPo and some are specified to operate down to -40C. See http://data.energizer.com/PDFs/la522.pdf and http://www.houseofbatteries.com/documents/U9VL-J.pdf.

Good printer, few problems
I bought a Xerox Phaser 6130N (mechanically similar to the 6125) last year for exactly that reason - my inkjet was always clogged up when I wanted to use it. I've had no problems with the 6130 even when I don't use it for weeks. I have only two criticisms of this printer: (1) when using the manual feed slot, it is very hard to get the paper aligned correctly - it often takes 2 or 3 attempts to get a printout that isn't skewed because the paper has gone through at an angle (printing from the tray is fine); (2) a replacement set of 4 toner cartridges at £50+ each costs more than the printer itself. So I will probably just buy black toner cartridges and buy a new printer when the colour ones run out. Wonder if I can get Xerox to pay to take away the old printer under the WEEE directive?
