Reprint problem

Im trying to reprint 4 copies of the same document to one printer with 4 trays. I made 4 copies of the printer (Brother HL-7050N), changed the tray setting to match that of each tray, 1-4. However, when i print, it only prints to the 1st tray. If i manually print to each tray, it works fine. What can i do to make this setup work? Each tray has different color paper for invoices.
Thanks

Sorin,

The printer settings come from the virtual printer, they can't be overridden in the physical printer.

yes, but i figured that it would resend the same print job to the other printer copies and use the settings from each to reprint. There is nothing in the settings i can do to change that>?

No there is nothing you can do to change this.
