[Android] Increasing Label Darkness with ZD420: can't find ZebraPrinterLinkOs


I'm trying to increase the sharpness & darkness of shipping labels printed with my ZD420 printer via an Android app.

I found sample code for this in the docs here ( but when I try it, my code crashes when I call ZebraPrinterFactory.getLinkOsPrinter(connection). The error I get is:

"java.lang.NoClassDefFoundError: Failed resolution of: Lcom/fasterxml/jackson/databind/ObjectMapper;"

[ANDROID] Is it possible to pull paper back after a calibration through ZPL commands? ZQ520 Printer

I have 2 models of zebra printer being supported by the application: RW420 and ZQ520.

The RW420 has a nice feature of pulling the paper back by pressing a button on the printer, but the ZQ520 doesn't have this feature and I'm wondering if it is possible to have the printer pull the paper back in after a calibration using ZPL commands. We wish to avoid manually reseating the paper after the calibration process.
