Bug#679117: printer-driver-ptouch: Incorrect Margins for PT9500PC and PT9800PCN

[Till Kamppeter <till.kamppeter@gmail.com>]

Thank you very much for the patch.

In your patch you write "Attention: Not tested on other printers." and 
indeed your patch changes code which affects all supported printers, not 
only the two models with which you were suffering the problem. This can 
easily break things on the other printers, assuming that most supported 
printers work correctly with the original code. If you are not sure that 
the change works for all printers you should do it in a way that it only 
applies if the printer is one of the models for which you have made the 
change.
