Changing Printer Trays During Print Job

问题

Is there a way to switch printer trays during a print job? I've been asked to put together a pick/pack slip program. They want the inventory pick slip to be printed on a sheet of colored paper, the pack slips to be on white paper, and they want it properly collated (pick, pack, pack, pack, pack; pick, pack, pack, pack, pack; ...).

I found some other threads on setting default trays, but didn't find anything on alternating trays during the job. Maybe I'm not searching on the right thing.

Don't know if it makes a difference, but our printer is an HP 3015n and the clients will be both XP and Win 7 Pro.

You can try something like this you have to reference System.Drawing.dll from the projects --> Reference--> Add

//Namespace:  System.Drawing.Printing
//Assembly:  System.Drawing (in System.Drawing.dll)

PrintDocument printDoc = new PrintDocument();
PaperSize oPS = new PaperSize();
oPS.RawKind = (int)PaperKind.A4;
PaperSource oPSource = new PaperSource();
oPSource.RawKind = (int) PaperSourceKind.Upper;

printDoc.PrinterSettings = new PrinterSettings();
printDoc.PrinterSettings.PrinterName = sPrinterName;
printDoc.DefaultPageSettings.PaperSize = oPS;
printDoc.DefaultPageSettings.PaperSource = oPSource;
printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);
printDoc.Print();
printDoc.Dispose();

To my knowledge no - you have to submit 2 jobs on a queue that basically only you use.

You can change printer tray with this code.

string _paperSource = "TRAY 2"; // Printer Tray
string _paperName = "8x17"; // Printer paper name

//Tested code comment. The commented code was the one I tested, but when 
//I was writing the post I realized that could be done with less code.

//PaperSize pSize = new PaperSize()  //Tested code :)
//PaperSource pSource = new PaperSource(); //Tested code :)

/// Find selected paperSource and paperName.
foreach (PaperSource _pSource in printDoc.PrinterSettings.PaperSources)
{
    if (_pSource.SourceName.ToUpper() == _paperSource.ToUpper())
    {
        printDoc.DefaultPageSettings.PaperSource = _pSource;
        //pSource = _pSource; //Tested code :)
        break;
    }
}

foreach (PaperSize _pSize in printDoc.PrinterSettings.PaperSizes)
{
    if (_pSize.PaperName.ToUpper() == _paperName.ToUpper())
    {
        printDoc.DefaultPageSettings.PaperSize = _pSize;
        //pSize = _pSize; //Tested code :)
        break;
    }
}

//printDoc.DefaultPageSettings.PaperSize = pSize; //Tested code :)
//printDoc.DefaultPageSettings.PaperSource = pSource;    //Tested code :)
