Hello Karl:
     Interesting comments regarding the networking issues but at some point, I have to say, that's enough paranoid stuff. I guess my comments about the clock chip are similar or at least on the edge of that. As for the printer power issue, you're probably right. I know that I vote in the garage of one of my neighbors and that isn't that unusual. Power would be even more of a problem there. I thought the batteries on UPS used a gel electrolyte and not a liquid. Still a nuisance in an emergency but perhaps not as bad as you make out. I also thought the most UPS's had power conditioning circuits that could handle surges and brown outs from both sides of the unit. The basic point we that I just wanted to mention that you don't have to deal with a warm up cycle on laser printers if you modify the settings.
As I've previously mentioned, I've been looking at ink jet printers for other purposes and I haven't yet seen one that doesn't present the output face up. Also, if we're using partially preprinted ballots as some have discussed, that requires the voter to put the ballot in 'up side or face down' which would be even more confusing. I've lost track of the times I've forgotten to put sheets into our fax machines correctly. Still the consensus seems to be edging towards ink jet units. I think Arthur or Alan's suggestion that perhaps we should quality both families of printers may be the best that can be done until extensive testing.
Thanks, Ed Kennedy

The problem with the laser printers is the huge instantaneous draw they
pull when heating the fuser roller. It's more than most consumer grade
UPS's can safely source. I just did some web searching and there is a
consistent clear message" "do not plug laser printers into UPS unless UPS
rating is >= 1400VA". A UPS fire, with an acid filled battery, is not
something you want to have to deal with.

In addition, at some point - a point very quickly reached in many school
rooms and garages and basements and other places used for polling stations
- the actual building circuits and outlets will be overloaded.

My guess is that with more than a couple of voting stations with laser
printers and we'll be blowin' the breakers (or fuses) on a typical polling
place or having the fire marshall shut the place down as a safety hazard.

I don't know how many of you have dealt with fire marshalls, but they look
at such situations in very simple and stark terms: if they don't shut it
down, people will die. So they do not take "no" for an answer.

The more I think about the printer issue the more I am convinced that
laser printers have drawbacks (such as the power drain issue) that make
them not just a poor choice but actually unacceptable, no matter how many
other good attributes they may have.
