""" Controls the panel buttons on the printer (e.g. FEED)
When enable is set to False the panel buttons on the printer will be disabled. Calling the method with
enable=True or without argument will enable the panel buttons.
If panel buttons are enabled, the function of the panel button, such as feeding, will be executed upon pressing
the button. If the panel buttons are disabled, pressing them will not have any effect.
This command is effective until the printer is initialized, reset or power-cycled. The default is enabled panel
buttons.
Some panel buttons will always work, especially when printer is opened. See for more information the manual
of your printer and the escpos-command-reference.
