Titolo: [?] Impostazione stampante

Saluti a tutti.
Avrei l'esigenza di far apparire la finestra che mi consente di "impostare"
la stampante, ma senza fare uso della Common Dialog perchè utilizzo un form
di stampa costruito da me con funzioni di stampa particolari, dal quale però
non riesco ad impostare la stampante.
Qualcuno sa dirmi come posso fare (con VB6)?
Grazie
         Alberto

Ti posto uno stralcio derivato da un progetto di Mauro Rossi.
Con una sola indicazione: visita il suo sito, è lui l'autore, non io.
Se non ricordo male qualcosa di analogo anche sul Sito Comune e sul sito
di Andrea Montanari.
E se, invece, ricordassi male, sono persuaso che comunque troverai molto
codice di esempio interessante e didattico.
