custom webview with browser print

Mina Samy Feb 13, 2019 4:44 PM

I have webview that I want it to communicate with the browser print urgently but for some reason it doesn't read any data from browserprint.js/ browserprint.exe. I use windows with this custom java webview and I have latest browser print 2.1 installed on the windows 7 and zebra barcode label printer GX430T (USB).

Everything works in firefox and chrome but I need the webview to work.

Would love some help.

Hello Mina,

The root cause of your problem could bee security restrictions or a deficiency of browser features in your java webview component. A webview component typically isn't a full-fledge browser. As you can see in BrowserPrint documentation it has support for following full-fledge browsers: Internet Explorer v11 or later, Chrome v51 or later, or Safari
Browser Print SDK | Link-OS | Zebra

As a solution you can try to use in your application a custom webview component that is based on Java Chromium Embedded Framework. See details here please:
1) chromiumembedded / cef — Bitbucket
2) How to integrate Chromium Embedded Framework (CEF) with java - Stack Overflow
3) https://medium.com/@daniel.bischoff/integrating-chromium-as-a-web-renderer-in-a-java-application-with-jcef-72f67a677db6

It could not be guaranteed you will have some success but there definitely a chance. As another option you can implement your application as a server and use full-fledge browser to access it and to run BrowserPrint.

  What about zebra java SDK? Is it promising? Does it need alot of time to implant?

    Hello Mina,
    
    I believe you can use Link OS PC-Java SDK and it's pretty much easy to add it into your project. Here is documentation on API and articles on how to use it:

      I have one more question. Is it good way to put "myprinter.sendCommand(command);" of sdk in loop to send the same command several times or there is another better way to achieve this ?
      
      Thanks in advance.
