LPT1 Printer redirection ThinOS9

Hello! 

Our environment: 
Wyse 3040 (ThinOS 9.1.5067) and Wyse 5070 (ThinOS 9.1.2101)
Citrix 1912 LTSR CU3 
Zebra GX430t printer connected through USB Cable

Problem: Can´t get LPT port to Citrix with ThinOS9. 

I can see the print in control panel as USB, a Test print works perfect. For a specific companies software I need to have it listed as LPT1 when doing net use. 
Any thoughts or suggestions? With ThinOS 8.6 and same config through ini files it works perfect. 

 

 

 

 

 

Thanks!
