printer supportHi
Here you are:
The first section is an API call to show the standard printer dialog, the
second section is an example from the Win32::NPRG module.
It detects your installed printers, you can select a printer, and it prints a
little example to the selected printer.
Regards
Gabor

I've only seen it done with a system() call to rundll32.exe. Something like
this:
# untested
$dll = "/Winnt/System32/mshtml.dll";
system("rundll32.exe $dll,PrintHTML $file");

Does win32 have any printer-type functions like "Select printer", "Printer
Properties", "Page Size", etc...
Thanks :)
