Re: I bet my weird printer problem can beat yours

I take my presumed "bad" printhead over to my daughter's house. I run
a test on her printer before I do anything and it works perfectly. I

Now, as I expected, no black with her printer. This seems to confirm
my printhead needs to be replaced.

I then put her "good" printhead back in and just for grins, run a
printing test. NOW HER PRINTER WON'T PRINT BLACK. It's as if my
printhead "infected" her printer.

I then ordered a brand new printhead, and installed in her printer or
mine, black does not print no matter how many times I reseat stuff or
change cartridges.

Many years ago I had a dot matrix printer on my desk. A cow-orker
asked if he could borrow it. Later he brought it back and commented
that he tried four printers on his computer and that they were all
dead, so he figured he needed a new ISA parallel interface board.

Then someone else came in and said that his printer stopped
working after my cow-orker borrowed it. I tested mine, and
it was bad too.

So I gently suggested, "have you ever considered the possibility
that your PC is a printer killer?"

Every one had a bad octal buffer IC. I replaced the chips
(with sockets to make future repairs easy) and the printers
worked. So I took his prallel port board out and hit it with
a hammer seeral times, and told him to order a new one. I
think he just did without.
