Proguard not supported by Printooth

[pitampoudel]

I have implemented Printooth on my Android app and is working perfectly fine with the debug app but when I build a release version of my app with Proguard enabled then the app crashes at run time.

io.paperdb.PaperDbException: Couldn't read/deserialize file /data/user/0/com.bigbusnepal/files/io.paperdb/paired printer.pt for table paired printer

here is the full crash report:
