    d[value]

    Data timeout function timeout value setting.

    If the d option is not specified with a model that supports the data timeout function, the data timeout function is enabled and the timeout value is set to 3 seconds.

    The method for specifying the timeout time is the following.

    1. If a value from 1 to 255 was specified for [value]: Time that was specified for [value]
    2. If 0 was specified for [value] : Data timeout function is ignored
    3. Other than the above: 3 seconds

    l[value](lower case “L”)

    Connection retry will be performed.

    The method for specifying the retry time is the following.

    1. If a value will not be specified (“l” only) : Timeout time specified by the getPort
    2. If a value from 0 to 300000 was specified for [value]: Time that was specified for [value] (units: milliseconds).
    3. If a value of 300001 or more was specified for [value] : Timeout time specified by the getPort
    4. Other than the above: Retry is not performed.

    l[value](lower case “L”)

    Connection retry will be performed when the target printer is in use by another host.

    The method for specifying the retry time is the following.

    1. If a value will not be specified (“l” only) : Timeout time specified by the getPort
    2. If a value from 0 to 300000 was specified for [value]: Time that was specified for [value] (units: milliseconds).
    3. If a value of 300001 or more was specified for [value] : Timeout time specified by the getPort

    • 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+
