NOTE

: 

The purpose of this manual is to serve as a reference to knowledgeable developers 

wishing to communicate directly with the LabelWriter printer without the use of printer drivers. 
Because the printer is a raster-based printer, this is not a simple task, and Sanford, L.P. reserves 
the right to limit development support for such implementations.
