Timeout on file write?

[Larry Bates]

Not tested, but you might want to take a look at:

second option, you could try something like:
p.write("whatever")
try:
    p.write("whatever")
    p.flush()

except:
      print "Write error on receipt printer"

p.close()

Just possible solutions, not tested.
