[Printing-architecture] Google Summer of Code 2008: JTAPI Library Project

[Petrie, Glen]

Lars,

(Sorry for the late reply - took a day off - need those once in while.)

I am glad you are interested in the JTAPI project.  I think you'll find it
fun and it will provide JTAPI the chance to become a main stream part of
Linux printing.

Thanks again for your interest in the JTAPI project.  I look forward to
working with you.

Glen
