Seems to work using 2.7 but not 3.2. On 3.2 it just closes all my
python sessions. Is this a bug? Can someone point me to a "How To" on
using a local printer in windows?
It's a bug. Starting IDLE from the command line, one can actually see the
error:
Exception in Tkinter callback
Traceback (most recent call last):
File "D:\apps\python32\lib\tkinter\__init__.py", line 1399, in __call__

IDLE is attempting to read an entry from its configuration file, but fails
because of a syntax error in the file (it's an error for a ConfigParser
entry, %s should be %%s). The same entry was fine for earlier IDLE
versions. As a workaround, you may edit the offending lines in your
configuration file.
Go to the idlelib directory; if you don't know where it is, just open idle
or Python command line and execute:
py> import idlelib
py> idlelib.__file__
'D:\\apps\\python32\\lib\\idlelib\\__init__.py'
In the same directory you'll find config-main.def; open it, and replace
these lines in the [General] section:
print-command-posix=lpr %%s
print-command-win=start /min notepad /p %%s
(%s should become %%s). Tested on Windows, but Linux should have the same
problem and temporary solution. You may need to roll this change back when
the code is corrected.
