Ho trovato quello che fa al caso mio grazie a questo codice che utilizzando un file txt esterno memorizza il numero che aumenta ad ogni pressione del tasto
ecco il codice che è possibile vedere tutto il contenuto a questo link: http://javascript.html.it/script/vedi/5961/dai-un-voto/

Ora devo cercare di inserire questa funzione in un file pdf che è questo : http://www.mediasitalia.info/prova/prova.pdf
devo fare in modo che ogni volta che premo stampa il numero 4600 aumenti progressivamente...mi potreste dare una mano ?
