• AutoSwitch Interface

  This function automatically detects ports for connecting to a printer. It detects connectable ports according to the following order of priority.

  1. USB

  2. Bluetooth

  3. LAN

  The procedure for this function is as follow.

  1. Prepare an environment so that Android Device can be connected with the printer via Bluetooth or LAN.

     • Pair Android Device with the printer via Bluetooth.

     • Connect Android Device and the printer to the same network (same segment).

  2. Connect Android Device with the printer via USB.

  3. Specify “AutoSwitch:” for portName, and then execute this method.

  4. If Android Device is successfully connected with the printer via USB, Step 3 is succeeded. If not, check the USB connection of Android Device and the printer, and then try Step 3 again.

  5. Specifying “AutoSwitch:” for portName can help Android Device automatically connect using other interfaces even if it is not connected with the printer via USB.

  If you want to change the printer to use, start over from Step 1.

  We recommend using this function in the following cases.

  • When you can prepare an environment so that multiple interfaces including USB can be used.

  • When the connected interface is frequently changed during operation.

  • When you do not want to know the connected port in the program.

  Important

  • Enable the USB serial number setting for the printer.

  • Do not perform the USB connection and Bleutooth pairing with any other printers except for the connected printer.

  • If using a LAN interface, prepare the environment so that UDP port 22222 can be used.

  Warning

  • This function may require more time until you can start printing than specifying a port directly.

  Following models support this function.

  Model	Firmware version
  mC-Print2	1.0+
  mC-Print3	1.0+

   • Data timeout function

     The data timeout function is a function which ignores the remaining print data when data was not sent to the printer within the specified length of time during printing.

     This function prevents corruption of the next print contents after the Bluetooth connection was disconnected during data sending.

     For usable models, refer to below.

     Model	Firmware version
     mC-Print2	1.0+
     mC-Print3	1.0+

     TSP650II	2.0+
     TSP650IISK	1.0+
     TSP700II	5.0+
     TSP800II	2.0+

   • Example of portSettings

   Printer connection environment	portSettings
   Uses TSP650II as the default setting.	“”
   Uses mC-Print3 with retry enabled by Ethernet interface.	“;l10000”
   Uses SM-L200 as the default setting	“Portable”
   If data is not sent for 10 seconds during printing withTSP650II, it operates the data canceling function.	“;d10”

3. ioTimeoutMillis Parameter

   timeout is a ioTimeoutMillis timeout controlled internally and is used for communication in the APIs This parameter guarantees that all of the below APIs will complete in a bounded amount of time, but does NOT guarantee the exact timeout length.

   Timeout length is 10 seconds if specified less than 10 seconds.

   .

4. Use share printer function with Apple AirPort Express

   Set AirPort Express IP Address for portName.

   Ex. TCP:192.168.1.2

   Set port number for portSettings.

   Increase the port number in sequential order from 9100 to 9109 until communication is successful.

5. getPort Retry Flow

   In case your application prints to bluetooth printers, the getPort method may sometimes fail to get status or print as the result of failing to connect with the Android Device depending on Android Device and a use environment.

   When getPort fails a StarIOPortException is thrown. Please repeat the operations mentioned in article II and III below.

   

   1. getPort fails (StarIOPortException is thrown)

   2. Wait for certain time (e.g. 500ms)

   3. Execute getPort again

   4. When getPort is successful, go to procedures such as printing or getting status

   Important

   The number of attempts to execute getPort to obtain a port handle depends on the Android Device . Some devices have a higher failure rate than others, and may require additional attempts to getPort. Please decide based on tests conducted with your Android Device .
