As promised, results of the attempt to defeat the 'Data Execution Prevention' problem ..... NIL
Adding Notepad.exe to the list of exempted programs had no effect at all - the
thing still refused to print
Removed and re-installed printer ... same result.
Finally tried to print out a page of print in MS Works and, hey presto!, it printed!! I can't even start to get my head around what is happening here,in particular why MS would want to incorporate such a feature anyway????? As far as I know, Notepad is an MS base program, so why does it see it as a problem?
Thank you to all the helpful subscribers - would still be happy to hear from anyone who knows WTHIH!!!
