Send commads to printer

[free free]

Hi,

i'am writing a python program and now i need to print some stuff. Before 
print i want to set the text to condensed text and to italic, so i have to 
send some esc commads to printer.

my code

pp=open("/dev/lpr","w")
pp.write(chr(27)+chr(15))
pp.write("This should be condensed\n")
pp.write(chr(27)+chr(52))
pp.write("This should be italic too\n\f")
pp.close()

what i get is text in normal font. I think chr(27) does not send the ESC 
char to printer.
Does anyone knows who to do this ?????????'

Thanks in advance for your help
