The "Send 2 Printer" application hooks into existing applications to

enable printing but you can also send the following data formats to

Send 2 Printer for printing from your own applications:

- HTML content

- Text

- Image

- Canvas draw commands (via serialized Picture)

- Canvas draw commands rendered to a Bitmap

For example:

Java:

void printCanvasExample()

{

// create canvas to render on

Picture picture = new Picture();

Canvas c = picture.beginRecording( 240, 240 );

// fill background with WHITE

c.drawRGB( 0xFF, 0xFF, 0xFF );

// draw text

Paint p = new Paint();

Typeface font = Typeface.create(Typeface.SANS_SERIF, Typeface.BOLD);

p.setTextSize( 18 );

p.setTypeface( font );

p.setAntiAlias(true);

Rect textBounds = new Rect();

p.getTextBounds( HELLO_WORLD, 0, HELLO_WORLD.length(), textBounds );

int x = (c.getWidth() - (textBounds.right-textBounds.left)) / 2;

int y = (c.getHeight() - (textBounds.bottom-textBounds.top)) / 2;

c.drawText( HELLO_WORLD, x, y, p );

// draw icon

Bitmap icon = BitmapFactory.decodeResource( getResources(), R.drawable.icon );

c.drawBitmap( icon, 0, 0, null );

// stop drawing

picture.endRecording();

// queue canvas for printing

File f = PrintUtils.saveCanvasPictureToTempFile( picture );

if( f != null )

{

PrintUtils.queuePictureStreamForPrinting( this, f );

}

}

The following post contains sample code to print the above formats and

include a sample "Test Print" eclipse project:
