Hi, I was trying to make bold characters and barcode. So I decided to change the mode to ZPL. but I couldnt

conn.open();

SGD.SET("device.languages", "zpl", conn);

ZebraPrinter zPrinterIns = ZebraPrinterFactory.getInstance(conn);
zPrinterIns.sendCommand("^FO350,50^AGR^FDwhatever,milk,butter,salt^FS");

Thread.sleep(500);
conn.close();

When I debugged it it say: SGD.GET("device.languages",conn) = "line_print"

Can u help me pls ?

Hi Shawn,

We have developed several samples code in Android Studio that implemented Zebra’s best practices. Also, there is a blog that explains aspects regarding the importance of the selecting the proper printer language. I have added another link to a forum request which will help you with the font software question.

Most of the libraries in our LINK-OS SDK support similar classes in iOS and Android. Please, follow the links below where you can compare the structure of each API.

IOS-API Documentation
ZSDK_API: Zebra API
Android-API Documentation
Zebra API for Android (build v2.9.2275)

ZPL – Printing Language set up:

Android:

SGD.SET("device.languages", "zpl", connection);
or
SGD.SET("device.languages", "hybrid_xml_zpl", connection);

iOS:

[SGD SET:"device.languages" withValue:@"zpl" andWithPrinterConnection:zebraPrinterConnection error:&error];
or
[SGD SET:"device.languages" withValue:@"hybrid_xml_zpl" andWithPrinterConnection:zebraPrinterConnection error:&error];

Check Printing language:

Android:
String printerLanguage = SGD.GET("device.languages",connection);

iOS:
NSString *printerLanguage = [SGD GET:"device.languages" withPrinterConnection:zebraPrinterConnection error:&error];
