printing an iFrame

Hi.
I’m using print-o-matic, and works like a charm! but I need to print a table inside an iFrame, and the short code doesn’t work (it prints the actual short code), then I made an object of the WP_Print_O_Matic object and called shortcode function, and works fine, but no icon or link shown and no option to print.
