[comp.periphs] Printhead Durability

   Is there any possibility of causing damage to a dot-matrix
printhead from using very thick multi-part forms?
   I use an Okidata 292 at work and I'd like to use it to print on
a 6-part form (original & 5 carbons, on fairly light paper).
I know the last one will be hard to read, but right now I'm writing
them by hand, which is worse (it takes too long to get someone to
type them). I don't see any obvious problems, but you never know
with these new-fangled things (I use a daisywheel at home).

I was having problems with a Imagewriter II with a Mac trying to print
5 part forms, because it would start jamming. At first, it seemed normal,
like there might be some stuff jammed into it, but then it started going
haywire. It turns out that the thick forms overheated the printhead and
caused the printed to think it was jammed. The company that provided the
forms pitched in and managed to make some 5 part forms that were thinner
than standard 5 parts.... This seems to have worked for the time being.
According to someone I know who used to work for Apple, it was a "design
flaw." ooops.
Anyways, does anyone have any experience with using a different type of
dot-matrix printer for printing multiple-part forms on a Macintosh?
Email responses would be appreciated
Thanks
