Trying to send commands (not labels) to Zebra printers using Python.
On page 574 of the documentation it shows:

Here's my code:
mysocket = socket.socket(socket.AF_INET,socket.SOCK_STREAM) host= "192.168.100.245" # verified IP address of Zebra printer port = 9100 mysocket.connect((host, port)) name_string= '''"sgd.name":null''' my_string= f'''{{}}{{{name_string}}}''' x = json.dumps(obj=my_string) mysocket.sendall(bytes(x,encoding="utf-8")) data= mysocket.recv(1024) print(data.decode('utf-8')) The printer responds to pings and other non-JSON Zebra commands sent to it (i.e. mysocket.send(b"~hs")). However, with the code above I wait for a long time and no response returns from the printer.
Tried multiple variations of the JSON formatting, what should I try next?
Per @bruan comment I tried the following variations but did not work:
my_string= '''"sgd.name":null"'''
my_string= '''{}{"sgd.name":null}'''
