Integrating A Program inside a LinkOS Printer

Hello, Does anyone know how can we integrate a small application inside a link OS printer. Any coding sample / API or something.

Briefly this is what I try to achieve. I have a server which connects to the link OS printer directly through Ethernet. But the server sends few images and text files. I need to convert them into ZPL and get the labels printed without connecting it to a PC or any outside software. I'm unable to edit the server side output either. Thank you so much for your help.

Xamarin Link-os iOS, Doesn't work without data connectivity. ZQ510


I have been working on an app using Xamarin with Link-os plugin and ZQ510 printer. The idea of ​​the app is that it can work in remote places where there is no internet connectivity.

The debug printing process always works. The iPhone can print without any problem with the Wi-Fi off and the data access off.

When the iPhone is disconnected from the PC and has some kind of data access, it is capable of printing. You can even remove the SIM card and connect it to a Wi-Fi without internet access and it will be able to print.

Link-OS SDK for Android | Permissions and Bluetooth API

Nowadays, most of our Zebra printers are equipped with Bluetooth (BT), Bluetooth Low Energy (BLE) or both (BT + BLE). There is a Bluetooth User Guide for Zebra printers, which covers how the Bluetooth technologies (both BT & BLE) are used in Zebra printer production lines, the security mode, pairing and configuration, etc.

Remote desktop printing, LinkOS

I have recently grabbed the C# LinkOS sample code from Git, to get a handle of a USB printer and it has been working fine on my local PC.

When it comes to running my application on a remote PC where the printer is connected locally, my application can no longer find any Zebra printers.

Remote desktop connection - Local resources includes the printers has PnP devices.
in the remote PC it shows 2 printers

LinkOS (Xamarin Android) Problems

I'm using LinkOS Version (1.2.0) (Xamarin Android) in my android application,but when I try to run the project I get the following error:

java.lang.OutOfMemoryError. Consider increasing the value of $(JavaMaximumHeapSize). Java ran out of memory while executing 'java.exe -Xmx1G -jar

I have the configuration 1G in the option Java Heap size, my Handheld isn't a Zebra hardware

Anyone have this problem?

Thanks in Advance

Printing From Websites Part 3

Hello Programmers!  I’m back again with my series on printing from within websites.  This time I’m going to talk about using a client program to print. 


The downside is that, until recently, you had to write a client program for every OS you wanted to support with your website.  There is still the possibility that you may want to do that, but there are now several options to serve this need.
