Ciao
ho un programma scritto in java ma ho dei problemi nella stampa.
quando stampo il programma mi stampa con un font troppo grande, ho provato a decompilare il programma e a modificare il font ma non mi varia la dimensione della stampa. inoltre come default mi imposta la pagina in formato letter mentre io vorrei cambiarla in A4
