How to print in a client side printer using APS.NET

Hello guys!

 

Recently we, at Dell in Brazil, changed the printer model to the GC420t and our applications don't working.

 

The old model TLP2844 works with a java applet, but this new model don't to anything with these applet.

 

My ideia it's change to ASP.NET but the main question is: How can I do this works?

 

Thanks in advance.
