So, I downloaded the TruPrint.deb here, installed it using iFile. But after that I can't "let the name of [TruPrint] appears" neither on searching in Cydia nor the packages under the manage tab in Cydia..
Which means I can't even uninstall the TruPrint!!
I've tried to uninstall it using WinSCP, but it didn't work out.
I'm now on the newest Cydia version. (1.0.3366-1)
