Hello!

You'll want to run the setup wizard HERE. It'll install the proper software & drivers on your computer. The same link will take you to the mobile app.

You misunderstood me.  I am dwveloping an app that will be sending information to my GX7021 printer.  I need to set  printer options from inside the app.  For instance; turning on or off duplex printing, selecting the papeer cardridge to use and other options.  Where can I find those codes to send to the printer?

I tried the Developer Support, but they won't let me in because I am a individual company with only my personal email.  How do I get in touch with them to clear this up?
