[python-win32] printing landscape in Windows

[Hans Becker]

Just about a month ago I started reading Learning Python by Mark Lutz.
It's a new paradigm for me. I have a whole bunch of old mainframe files
with carriage control characters as the 1st character in each line.
Well, a got a very simple script working except I need to be able to
print landscape on my pc printer. Does anyone by chance have sample code I
could cut and paste to print landscape? I'm running Windows 7 Pro and
Python 2.7


#prt1a is a copy of prt11

import os, sys, tempfile
import win32api, win32print

printer_name = win32print.GetDefaultPrinter ()
hPrinter = win32print.OpenPrinter (printer_name)

hJob = win32print.StartDocPrinter (hPrinter, 1, ('alfie', None, "RAW"))
win32print.StartPagePrinter (hPrinter)

for line in open('alf1'):
    cc = line[0]
    line = line[1:]
    line = line.rstrip()
    
    if   cc == '1': line = '\f' + line
    elif cc == ' ': line = '\n' + line
    elif cc == '0': line = '\n\n' + line
    elif cc == '-': line = '\n\n\n' + line

    line = line + '\r'   # takes care of the overprinting
    win32print.WritePrinter(hPrinter, line)

win32print.WritePrinter(hPrinter,"\f")
win32print.EndPagePrinter (hPrinter)
win32print.EndDocPrinter (hPrinter)
win32print.ClosePrinter (hPrinter)


my test data 'alf1':

1                 QWDDNNNDNDN
++2                 /111111111
++2a                XXXXXXXX11
3                ZDDDDNDNDNNN
++4               #/1111111111
++4a              #XXXXXXXXX11
++4 b             #WWWWWWWWWW1
5   MMMMMMNMMMMMMMMNMNNNNMNNNM
++6  IIIIII1IIIIIIII1I1111I111I
++6a IIIIII1IIIIIIII1I1111I111I
7   NNMNNNNNNNNNNNNNNNNNNNNNMM
++8  11I111111111111111111111II
