This kind of thing is very tricky in Windows -- much trickier than it should be -- and I've been doing Windows programming for a very, very long time. I have a wxPython application that I use to print envelopes through my Dell 3100 laser printer. The printer has a multi-purpose tray that I keep stocked with #10 envelopes. It's very convenient, and since my handwriting it terrible, the people I write to appreciate it as well. Recently, I upgraded from Python 2.5 to Python 2.7, and suddenly my envelope application stopped working. It would print in portrait mode on the normal paper stock, instead of selecting the envelopes in the multi-purpose tray. It required two or three hours of fairly intense hacking before I figured out a recipe to make it work again. If I had not previously been a GDI driver developer, I doubt that I could have figured out the DEVMODE magic that was required. -- Tim Roberts, t...@probo.com Providenza Boekelheide, Inc. ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

I think this is dependent on the printer driver.
Some use the paper size defined by the the form,
and others use the PaperSize member.

Hi,
I am adding some printers connection as a user with
win32print.AddPrinterConnection().
Afterwards I want to set paper size to A4 (I have no idea why Polish
Windows XP sets it to Letter by default) with this example code:
==
import win32print
import win32con
import win32gui
import pywintypes
printer = r'\\drukarki\kp01'
handle = win32print.OpenPrinter(printer, {'DesiredAccess':
win32print.PRINTER_ACCESS_USE})
devmodeSize=win32print.DocumentProperties(0, handle, printer, None,
None, 0)
devmode = pywintypes.DEVMODEType(devmodeSize -
pywintypes.DEVMODEType().Size)
win32print.DocumentProperties(0, handle, printer, devmode, devmode,
win32con.DM_IN_BUFFER | win32con.DM_OUT_BUFFER)
print 'FormName before: %s' % devmode.FormName
print 'PaperSize before: %s' % devmode.PaperSize
devmode.FormName = A4
devmode.PaperSize = win32con.DMPAPER_A4
devmode.Fields = devmode.Fields | win32con.DM_FORMNAME |
win32con.DM_PAPERSIZE
print 'FormName set: %s' % devmode.FormName
print 'PaperSize set: %s' % devmode.PaperSize
info = win32print.GetPrinter(handle, 9)
info[pDevMode] = devmode
win32print.SetPrinter(handle, 9, info, 0)
devmodeSize=win32print.DocumentProperties(0, handle, printer, None,
None, 0)
devmode = pywintypes.DEVMODEType(devmodeSize -
pywintypes.DEVMODEType().Size)
win32print.DocumentProperties(0, handle, printer, devmode, devmode,
win32con.DM_IN_BUFFER | win32con.DM_OUT_BUFFER)
print 'FormName after: %s' % devmode.FormName
print 'PaperSize after: %s' % devmode.PaperSize
win32print.ClosePrinter(handle)
win32gui.SendMessageTimeout(win32con.HWND_BROADCAST,
win32con.WM_DEVMODECHANGE, 0, 0, 0, 2000)
==
The output looks like this:
==
FormName before: A4
PaperSize before: 1
FormName set: A4
PaperSize set: 9
FormName after: A4
PaperSize after: 1
==
So, as you can see - FormName changes, but PaperSize does not.
Am I doing something wrong here? I've spent a lot of time trying to
solve it, yet came up with nothing.
Do you have any suggestions?
Thanks,
Filip Zyzniewski
