I am using a Zebra ZT 411 printer, but I have two issues. First, I want to use the RS-232 serial port, but when I install the driver, there is no option for it in the printer settings; only options like network and Bluetooth are available. Second, I want to connect to the printer via the network. In fact, when I ping the printer, it shows as connected, but when I try to do a test print, it doesn't work. I would appreciate your guidance.
