I tryied something similar, but the problems is that the printer that i will use is a shared printer from another pc, when I try to connect to the printer with $host= \192.10.10.228\ZDesigner GC420t (EPL), return The requested name is valid but no data of the requested type was found.
How can I solve it?

@BerndSchranz does this solution work on zebra gc420t printer?

@skagamer12 did it work for you on the GC420t printer?

@erighetto does this solution work on zebra gc420t printer?
