Titolo: [?] - Ritrovare i Messaggi

Buongiorno, un paio di mesi fa avevo fatto una domanda su come si stampa in
orizzontale nel DataReport
Una splendida ragazza ke non ricordo il nome mi aveva risposto.Avevo salvato
il msg ma adesso lo perso
Come posso recuperarlo? O c'è qualcuno gentile che può dirmi come si fa a
stampare in orizzontale?
grazie anticipatamente a tutti e buon lavoro
bye Roberto
