The following works on Windoze 98 and bombs on Windoze XP.
It crashes either on the last EnumPrinters or the CreateDC.
Could it possibly have something to do with DLLs - mine from 1999 to
the computer that I tested it from 2002????
Thanks for any help,

From MSDN:
PRINTER_ENUM_DEFAULT Windows 95/98/Me: The function returns information about the default printer.
So you'll have to enumerate different printer type on nt/2k/xp.

Since I posted this message I have found out a few more things.
I have a copy of ENUMPRINTERS from 1999. On msdn there is a much later version
of ENUMPRINTERS which I am unable to print a copy of.
I looked at the possibility on ordering an API SDK but from what I read it implies
that it won't work on Windows 98
So from my above code it seems that I must be able to tell what operating system
I am on and then modify ENUMPRINTERS accordingly. First I don't know how to
do that and 2nd what a hassle this is.....
