For Hp printers you can use Hp-eprint by finding the email address of your Hp printer and then you can use following code to send mail to your priner.As You send the mail the attached document gets printed on your Hp Printer.
private void openHpeprint() {
File file = new File(folder + "/" + fileName);
if (file.exists()) {
Intent emailIntent = new Intent();
emailIntent.setAction(Intent.ACTION_SEND);
/* Uri uri = Uri.fromFile(file);*/
Uri uri = FileProvider.getUriForFile(mContext, mContext.getApplicationContext().getPackageName() + ".provider", file);
emailIntent.setFlags(FLAG_GRANT_WRITE_URI_PERMISSION);
emailIntent.setFlags(FLAG_GRANT_READ_URI_PERMISSION);
// set the type to 'email'
emailIntent.setType("vnd.android.cursor.dir/email");
emailIntent.setPackage("com.google.android.gm");
String to[] = {"yourHpprinteremailaddress@Hpeprint.com"};
emailIntent.putExtra(Intent.EXTRA_EMAIL, to);
// the attachment
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
// the mail subject
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
try {
startActivity(emailIntent);
} catch (ActivityNotFoundException e) {
Logger.LogError(TAG, "No Application Available to View Pdf");
}
}
}
