Printing to a TM printer

The UB-E04 is equipped with LPR protocol as a general printing protocol. It is easy to print by using LPR
because the printing is also supported by the operating system.
However, the command statuses sent by the printer are ignored because the printing by protocols applies
only to output of the printer.
The UB-E04 supports direct printing via the TCP PORT9100. It is possible to control the printer directly by an
application with the ESC/POS commands through writing and reading to the TCP PORT9100.
