Windows下打印函数库

/*
This source code was copied from a microsoft example program 
and modified to work in the context of this printing function
library. I DO NOT claim authorship of this code only the minor
modifications made to the parameters and elimination of some
of the code that was superflious fo our implementation. We did
modify the code slightly to work in a 32 bit enviornment
