No doubt sensing a little heat from Apple's own AirPrint, Epson and Thinxstream have now announced that their PrintJinni wireless printing app for iOS devices will soon be available completely free of charge -- a permanent price drop, mind you, not simply a holiday promotion. Unfortunately, you can't grab it for free just yet, as it will still demand the regular $6.99 until the App Store processes the price change, which is apparently expected to happen before the end of the month. Head on past the break for the complete press release.
