Q4-1: Which interfaces are available for Star TSP600, TSP700 and TSP800?
 TSP100U is only USB interface.
TSP600/650/700/700II/TSP800/1000 are supplied with either a Centronics Parallel interface or an RS232 compatible 25pin Serial interface.
Ethernet or USB interfaces can also be bought separately.
TSP828L is supplied with dual interface including 9 pins serial and USB.
All interfaces are fully bi-directional.
The other models, please refer below table:-

Q4-2: Is there an RS422A interface available?
TSP400, SP300 has optional RS422A interface, but other models don¡¯t have RS422 interface.

|
Q4-3: Why won't my serial printer work with the raster drivers?
Serial printers cannot use Raster drivers. Serial port communication is too slow to utilize raster drivers. You can always purchase a parallel or USB interface for the printer to make the printer compatible with raster drivers.
|
|
Q4-4: What happens if I set handshake setting incorrectly?
In case of larger data printing such as image data printing, middle area of the printing will not be printed. Normally, Xon/Xoff is default setting in Windows, but Star¡¯s default handshaking is DTR (hardware) communication setting. It can be changed by DIP SW.

|
Q4-5: Why cannot my printer be ON when I connect the parallel printer to PC?
It depends on the reset signal status of PC. Some of general PC keeps low level of output of reset #31 when LPT port is closing. To avoid this phenomena, you can set external reset to be invalid by DSW 1-5(TSP600/650/700/700II/800/828L/1000) or MSW6(SP700 & SP500).

Q4-6: What is the recommended connection of RS232C to PC?
Please connect to PC as following assignment. The arrow shows the data flow direction. Please pay attention the cable. It should be ¡°cross cable¡±.
|
|
Q4-7: What is DTR mode?
DTR mode is so called ¡°hardware handshake¡±. In the DTR mode, the DTR signal is used as a BUSY signal for printer control. A SPACE indicates that the printer accepts data, but a MARK indicates that the printer rejects data.
If there is no error after the power on, the DTR signal line changes to ¡°SPACE¡±.
When the host confirms that the DTR signal line is set to ¡°SPACE¡±, the host sends the data text via the RXD signal line tothe main logic board. Also, the main logic board will set the DTR signal line to ¡°MARK¡±.
|
|
Q4-8: What is Xon/Xoff mode?
Xon/Xoff mode is so called ¡°software handshake¡±. When the printer is ready to receive data, it periodically sends an X-ON (<DC1>=11h) signal to the host. When the printer is not ready, it sends an X-OFF (<DC3>=13h) signal to the host. In case of Xon/Xoff mode, printer doesn¡¯t check the DSR status to send a data to host.
