試一下printer-draw-bmp在本手冊的評論中有很好的例子。

$im = imagecreatefrompng('kitten.png'); 
$randomName = uniqid() . '.bmp'; 
imagewbmp($im, $randomName); 

$handle = printer_open("HP Photosmart 5520 series"); 
printer_start_doc($handle, "My Document"); 
printer_start_page($handle); 

printer_draw_bmp($handle, $randomName, 0, 0); 

printer_end_page($handle); 
printer_end_doc($handle); 
printer_close ($handle); 

unlink($randomName);
