While most printer drivers being released for the mobile platform are generic (so you wind up printing only in black and white and without all the bells and whistles you've grown accustomed to), it's still possible to print from Android with PrinterShare Mobile Print. Printer manufacturers are only now starting to recognize the validity of printing from mobile devices. But the mobile platform is an entirely different beast. Printing is an incredibly challenging issue - even desktops have issues with printing. A lot of people have asked me how to print from the Android platform.
