Re: Send output to printer
Jorgen Bodde
It depends on how your printer can be accessed. Is there a driver for
it? The most simple way might be using ShellExecute (under windows)
but I found no way to supress the print dialog.
Another way is using win32com module and instantiate an IE automation
object, which you feed a HTML page and issue a print. Be careful about
printing too fast allow it 4-5 seconds to process or successive print
jobs will fail.
Here is a snippet of code to get you on your way;
from win32com import client
ie = client.Dispatch("InternetExplorer.Application")
ie.Navigate(fn) # fn = filename (to temp file) to print
time.sleep(2)
ie.ExecWB(6, 2)
time.sleep(2)
ie.Quit()
ie = None
For successive prints it is better to instantiate one IE object per
multiple print jobs, but once done, release it and set it up again.

If it's connected to the PC's parallel printer port then you could try
writing to "LPT1:":
printer = open("LPT1:", "wb")
printer.write("Hello world!\r\n")
printer.close()
Note that in order to advance to the next line you'll need to write a
carriage return and linefeed ("\r\n"), as above.
