HitiPPR_GetPrinterInfo

the constructor

This class is declared as:

public class HitiPPR_GetPrinterInfo extends HitiPPR_PrinterCommand

It's constructor (which is called from SendPhoto()), does not look very interesting

    public HitiPPR_GetPrinterInfo(Context context, MSGHandler msghandler)
    {
        super(context, msghandler);
        m_AttrProductIDString = null;
        m_AttrFirmwareVersionStringLength = -1;
        m_AttrFirmwareVersionString = null;
        m_AttrSerialNumberStringLength = -1;
        m_AttrSerialNumber = null;
        m_AttrBatteryLevel = null;
    }

(The super's constructor is also boring. It simply initializes a whole bunch of variables.)

start()

Well, not sure what is going on here. start() has not been implemented by HiTi, but takes us all the way in to Java.lang:

    /**
     * Starts the new Thread of execution. The run() method of
     * the receiver will be called by the receiver Thread itself (and not the
     * Thread calling start()).
     *
     * @throws IllegalThreadStateException - if this thread has already started.
     * @see Thread#run
     */
    public synchronized void start() {
        checkNotStarted();

        hasBeenStarted = true;

        VMThread.create(this, stackSize);
    }
