The MyQ Lexmark Embedded terminal is a web based embedded terminal; no applications are running directly on the printing device, all files are saved in the MyQ directory and the device exchanges data with MyQ via the HTTP protocol. The communication port is set manually within the installation of the terminal.
The proper function of the MyQ Lexmark embedded terminal depends on the below:
.NET 4.7.2 or newer, or .netcore 2.1 needs to be installed on the MyQ Print server.
The administrator's password has to be set on the printing device.
The IP or Hostname of the printing device has to be valid.
