[python-win32] Printing with COM triggered by a python cgi script

[Douglas F. Schieszer]

I am trying to learn how to create a python cgi web application.  I have
created a module that I want to use to print a reciept using the python
com interface that is based on the "Interfacing with COM" example in
learning python 1st edition.  I will include it below.  This
print_testdrive() function works fine when called from a command line with
the proper objects as arguments, but when I execute it as part of a cgi
script it gives no errors but does not print anything.  Any ideas what I
have done wrong?

reciept.py:

from win32com.client import constants, Dispatch
WORD = 'Word.Application'
False, True = 0, -1
import string

class Word:
	def __init__(self):
		self.app = Dispatch(WORD)
	def open(self, doc):
		self.app.Documents.Open(FileName=doc)
	def replace(self, source, target):
		self.app.Selection.HomeKey(Unit=constants.wdLine)
		find = self.app.Selection.Find
		find.Text = "%" + source + "%"
		self.app.Selection.Find.Execute()
		self.app.Selection.TypeText(Text=target)
	def printdoc(self):
		self.app.Application.PrintOut()
	def close(self):
		self.app.ActiveDocument.Close(SaveChanges=False)

def print_testdrive(customer, vehicle, appointment):
	word = Word()
	word.open(r"c:\Program Files\Apache
Group\Apache2\htdocs\templates\testdrive.doc")
	if customer.nameprefix:
		word.replace("nameprefix",customer.nameprefix)
	else:
		word.replace("nameprefix", " ")
	if customer.firstname:
		word.replace("firstname",customer.firstname)
	else:
		word.replace("firstname", " ")
	if customer.middlename:
		word.replace("middlename",customer.middlename)
	else:
		word.replace("middlename", " ")
	if customer.lastname:
		word.replace("lastname",customer.lastname)
	else:
		word.replace("lastname", " ")
	if customer.namesuffix:
		word.replace("namesuffix",customer.namesuffix)
	else:
		word.replace("namesuffix", " ")
	word.replace("time",appointment.time)
	word.replace("date",appointment.date)
	word.replace("reservation",appointment.reservation)
	word.replace("VIN",vehicle.VIN)
	word.replace("Make",vehicle.Make)
	word.replace("Model",vehicle.Model)
	word.replace("Color",vehicle.Color)
	word.replace("OptionPackage",vehicle.OptionPackage)
	word.replace("Accessories",vehicle.Accessories)
	word.replace("ModelYear",vehicle.ModelYear)
	word.printdoc()
	word.close()
