Hi, and welcome to the forum!
In fact, there are two major ways to get your ZIM running:
-
@Nightmare and @Jaesin have found a way to manipulate the software of your ZIM to make it work,
-
others like @BDub and @jpod (and me) took their Machine apart and use a Raspberry Pi to print.
Both ways work fine, and although I´m one the RasPi-users, I would recommend you to try the leave-your-hardware-original way. You can still switch to a RasPi if you don´t like the standard software.
So, maybe @Nightmare or @Jaesin could make some step-by-step manual how to install the jailbroken software (best with links where to get it) and convert a factrory ZIM to a printing one.
