Epson E02 manual Commands Sent to a TM Printer When the Power is On, Monitoring of the ASB status

4.3 Commands Sent to a TM Printer When the Power is On

When the power is turned on, the UB-E02 transmits the following commands to the TM printer and maintains the statuses. The UB-E02 acquires printer information by GS I and monitors the printer status through the TMNet WebConfig using the GS a 255 command.

ESC/POC command descriptions:

•GS I 1: printer ID

•GS I 2: printer type ID

•GS I 3: printer ROM version ID

•GS a FFh: Enables ASB status

Note:

When the power is turned off or the printer is off-line, the commands above are not transmitted.

4.4 Monitoring of the ASB status

The UB-E02 monitors the ASB statuses transmitted from TM printers to control the printer statuses from host computers. The printer can know the statuses by remote using the TMNet WinConfig or the TMNet WebConfig.

If the printing data includes commands that disable the ASB such as ESC @ and GS a 00h, the ASB status from the TM printer will not be transmitted afterward when the printer status is changed and the UB-E02 cannot monitor the status of the TM printer.

To monitor the printer status, when there is a command that disables the ASB in a data string sent by an application to the TM printer, transmit a command that enables the ASB.

4.5 The Priorities of Printing

The UB-E02 permits up to 3 requests of connecting regardless of the lpr/port9100 protocol. Printing by the TM printer is given the first priority. Data transmission is blocked for other requests until the first connection is closed (explicit close or close by time-out).

4.6 Time-out for Connection

If there is no data transmitted from the host for 5 minutes, regardless of the protocol, lpr/ port9100, the UB-E02 closes the connection. To continue the connection, the host needs to send the UDP command explicitly.
