device ID
When the printer receives the hexadecimal values 00H or 04H, the printer
responds in the following manner:
00H: The printer enters reverse channel mode, allowing data to be sent to
the host.
04H: The printer sends the device ID to the host; the device ID consists of
the following strings:
<00H><4EH>
