问题 I would like to add wireless printing to my android 2.2 application which is targeted for the Galaxy tablet. I see that the internet browser has a print option so I am assuming that an activity hook must exist, and I was hoping that someone has figured this out. I have found a possibility using the PrinterShare application from Mobile Dynamix, but my preference would be to no require a 3rd party.

问题 Hi android programmers, I've been struggling all day long on a problem that seems strange and with no solution. What I seek is some guidance and some previous experiences. For testing purposes I have a Motorola Xoom , Galaxy Nexus Tab , Galaxy Nexus phone , and a Galaxy Tab 10.1 . The main testing application is developed for/in the Galaxy Tab 10.1 .
