> How do you send data to the printer?
Theeasy way, for text is:
os.system('lpr foo.txt') # *nix
OR
os.system('Print foo.txt') # DOS
Or just assign stdout to prn:
Or open PRN: as a file
For fancier work you are probabluy best to generate
an HTML file or PDF and print that using the native
tools as above.
If you must do it in Windows native printing then its HARD!
You need to create a device context on the printer and
draw the output using GDI commands. The theory is that
the same GDI calls generate the display and the print
(hence WYSIWYG) but in pracxtice its not that simple!
On *nix its usually via runoff macros of some type.
