command line tool for print picture?

Question

My program need to print a curve, my solution is changing the curve into a picture, and this picture file (xxx.png) can be printed by using the default windows picture print

Answer 1

I had a similar problem but I also needed way to control scaling (needed for barcode work) and always have the image centered.

I wrote an Open Source tool called ImagePrint to do just what you want. It's written in VB.Net as a console app. At the moment, it only prints to the default printer.
