Código de Barras en PHP aquì està la parte del ticket que imprime el còdigo de barras)
Código:
el cual hace referencia a este archivorequire_once("barcode/php-barcode.php");
printer_draw_bmp($handle, barcode_print($barcode,encoding,'2',mode),110, $y); $y=$y+200;
Código:
el problema es que no me lo muestra como bmp, pero si lo cambio por jpg si lo muestra, podrìan ayudarme, soy ateo pero dios se los pagarà con muchos hijos require_once("php-barcode-configure.php");
