I am using Browser Print on Windows to an iMZ320 printer. When the printer is connected via USB the whole flow of the application works fine, the ~HQES request for printer status returns information and I can send commands and items to print successfully.
When I change the printer to be connected to on the network I can print fine using Browser Print but the ~HQES response is empty. I can take the command to print and send it via Postman and it works fine. When I send the ~HQES command in Postman I get an empty response, so it's not that it's the Browser Print code masking the response in some way. When I use the Zebra Setup Utilities to send the ~HQES command I get the response :
ERRORS: 0 00000000 00000000
WARNINGS: 0 00000000 00000000
Please could you let me know how I can get hold of the printer status information for the networked printer?
I have the same issue but being able to print to a network connected (IP) Zebra printer ZDesigner GX420t.
Did you get to work?
