Thank you, Maxell.
I had already had a sort of look at that reference while I was wrestling with the problem.
Many years ago, on steam radio, there was a 'comedian' called Harry Hemsley who used to act out a skit with a supposed family of three children, Winnie(the oldest), a middle child and Horace, the youngest, who used to make noises, unintelligible to anyone other than Winnie. The catch-phrase was "What did Horace say, Winnie?" Oh, how we laughed!
That MS reference document was the written equivalent of a Horace output!
The supposed answer to the problem is to disable DEP on the errant program - in this case, the printer. Fine, except that the printer program does not appear in the Program File listing. There would also appear to be some method of totally disabling this latest MS idiocy but deciphering the 'geek speak' may prove to be beyond me
Can anyone out there
a. translate the MS verbiage into plain english
and/or
b. explain why the original printer installation worked fine and didn't generate this "protection" measure but the re-install does?
TIA
