How to change the default "Portrait Orientation" to Landscape in Android Print Framework?

Question

Is there a way to change default portrait preview to landscape in print framework?

I have tried below -

PrintAttributes attrib = new PrintAttributes.Builder()
.setMediaSize(PrintAttributes.MediaSize.NA_LETTER.asLandscape())
.setMinMargins(PrintAttributes.Margins.NO_MARGINS)
. build();

and also tried below -

PrintAttributes attrib = new PrintAttributes.Builder()
.setMediaSize(PrintAttributes.MediaSize.UNKNOWN_LANDSCAPE)
.setMinMargins(PrintAttributes.Margins.NO_MARGINS)
. build();

I've noticed that it doesn't change the page orientation to Landscape

In above print setting dialog if I do change the orientation to landscape then and only then the print preview page changes orientation to Landscape. Can this be done programmatically? I want default preview in Landscape.

I used below Code:

PrintManager printManager = (PrintManager) this.getSystemService(Context.PRINT_SERVICE);
    String jobName = this.getString(R.string.app_name) + " Document";

    PrintAttributes attrib = new PrintAttributes.Builder()
            .setMediaSize(PrintAttributes.MediaSize.UNKNOWN_LANDSCAPE)
            . build();

    printManager.print(jobName, pda, attrib);

My Result:
