Zebra ZQ520 Printer - Update Firmware - Using LinkOS SDK iOS

We are having issues with the Zebra printer disconnecting when we send the firmware update to the iOS device. When we push the firmware to the device, the printer changes its text to "Downloading Firmware" but never finishes.

Here is a code snippet

id<ZebraPrinterConnection, NSObject> conn = [self getPrinterConnection:reject];

if (conn != nil) {
// Get the printer
NSError* printerError = nil;

[conn open];
[NSThread sleepForTimeInterval:1.0];

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

Hi,

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 (http://techdocs.zebra.com/link-os/2-14/android/) 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;"
