Geoff, 


Get hold of the excelent win32 extension for python (url????)

Then somthing like this: (untested since I wrote it about a year or two ago!)


import win32print
printer_list=[]
for p in win32print.EnumPrinters(win32print.PRINTER_ENUM_CONNECTIONS):
    printer_list.append(p[2])
for p in win32print.EnumPrinters(win32print.PRINTER_ENUM_LOCAL):
    printer_list.append(p[2])
default_printer=win32print.GetDefaultPrinter()


printer = win32print.OpenPrinter(default_printer)

jid = win32print.StartDocPrinter(printer, 1, ('Page %i' %copy, None, 'RAW'))
bytes=win32print.WritePrinter(printer, open(file, 'rb').read())
win32print.EndDocPrinter(printer)
win32print.ClosePrinter(printer)


Please not this is sending a file's contents to the printer (as it happens a 
postscript file)  


Cheers
