HI,

You are don't understand me.

In my job there are two laser printer, the one have 3 tray of diferents size, the other have 5 tray. Each document type have diferent size, hence we are locate 3 type of paper in each tray of printer, an so, to print each document type for each tray.

In this moment, this is posible only showing the printer prompt, the user select the tray for the document and so to print.

1. How, to select by program, the tray for one document, without to show the printer prompt?,
2. By poscript code to the printer, to set in run time the tray that will use the document type next to be to send to the printer. how to do this?.

thanks.
