Works great on old iPhone 3G!
This review refers to an older version of this app that still works on my dads old iPhone 3G. We have a Samsung ML-2525W black & white laser printer. It took about 2 minutes for this app to process a 17 page text document and another minute to send it to the printer and print. I was amazed. Ive not tried any graphics test since its not a color printer.
