It is easy to print by using lpr protocols because the printing is also supported by the operating system. However, the command statuses sent by the printer are ignored because the printing by lpr applies only to output of the printer. The UB-R04 supports direct printing by 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. LPR HOST UB-R04 TM Printer 4 TCP port 9100 49
