Make MechComp printers subject to jamming, like regular printers.

I think this was brought up by a round where a dude hooked up 10-20 thermal printers to the loafer. I actually got d/c'ed, so I don't know the after effects.

Stuff like that is really more of a loafer (and people, but I've done worse) problem than a thermal printer problem. Though having that many run on a single tile is kinda silly. Maybe have them check to see if there's another printer on that tile? One printer per tile shouldn't really lag the server. At least it never has for me.
