I would like to know how to distinguish between a Program Printer such as
'Acrobat PDFWriter' and a Hardware Printer such as HP's one and a Network
Printer. Would it be possible to distiguish each of 'Acrobat PDFWriter', 'HP
desKjet', shared printer(which the port is started with '\\'), and a
printer(using tcp/ip port) through printer server, if they are installed on
a PC. Now I'm trying to get the printer information with "EnumPrinter()",
but it's not easy to get known how different.
