Greeting, i am trying to print to different tray/bin.. i have tried to set paper tray number using following code:
my printer has 4 trays.. i tried 1 to number 4 that didn't work.. so, i made a demo tool to list the printer trays, but strangely it shows same trays number for most of my printers :( but still when i try to print tray 15 and 257 (using 1st printer name), both print to same/default tray :( and more strange is that the 2nd printer on the list only have 1 tray, but qpl also shows same trays number for that one too? :( so? what i am doing wrong here? thanks in advance for upcoming help best regards

Hi Hassan,
To check about the real printer names i use: GetPrinterNames. To check about existing printer bins i use: GetPrinterBins. Doing the output the following syntax should help: if ( prname = 'default' ) Then PriName := QP.GetDefaultPrinterName; if ( prname <> 'default' ) then PriName := prname; // . . . propt := QP.PrintOptions(pscal, rotate, fname); if ( bin > 0 ) Then begin cPriName := QP.NewCustomPrinter(PriName); QP.SetupCustomPrinter(cPriName, 9, bin); end; if ( pend = 9999 ) then pend := pc; // pagecount for i := 1 to copies do begin if ( bin > 0 ) Then QP.PrintDocument(cPriName, pstart, pend, propt) // with bin else QP.PrintDocument(PriName, pstart, pend, propt); // without bin end; |

Do you read all at "for default source" (New Value)?
https://www.debenu.com/docs/pdf_library_reference/SetupCustomPrinter.php There should be a problem... After each code line you can check the returning value of the call from one line before. 1 means okay / 0 means error Perhaps this helps one step further? |

Before printing, you can set the paper box that the printer will use in advance.
The following example achieves a more flexible function: changing the paper box used during the printing process. If you only need to set up the paper box before printing, you can modify the code yourself. ============================== code: Printer.BeginDoc; //dosomething...print //--------- Changing Trays .... ----------------- Printer.GetPrinter(device, driver, port, hDMode); if (hDMode <> 0) then begin pDMode := GlobalLock(hDMode); if Assigned(pDMode) then begin pDMode.dmFields := pDMode.dmFields or DMBIN_MANUAL; pDMode.dmDefaultSource :=GetTraysID(); winapi.Windows.EndPage( Printer.Handle ); If ResetDC( Printer.canvas.Handle, pDMode^ ) = 0 Then showmessage( 'ResetDC failed, '+SysErrorMessage(GetLastError)); GlobalUnlock( hDMode ); winapi.Windows.StartPage( Printer.Handle ); Printer.Canvas.Refresh; end; //-------------------------------------------------- //dosomething...print Printer.EndDoc; end; function GetTraysID()(TraysName: string; adevice, aport: PWideChar): Word; var i, rslt: Integer; tBinNames: array of Tbinname; BinCodes: array of Word; begin Result := DM_DEFAULTSOURCE; rslt := devicecapabilitiesW(adevice, aport, dc_binnames, nil, nil); if rslt > 0 then begin setlength(tBinNames, rslt); setlength(BinCodes, rslt); try if devicecapabilitiesW(adevice, aport, dc_binnames, @tBinNames[0], nil) = -1 then begin setlength(BinCodes, 0); setlength(tBinNames, 0); raise exception.Create('error tbinnames'); end; if devicecapabilitiesW(adevice, aport, DC_BINS, @BinCodes[0], nil) = -1 then begin setlength(BinCodes, 0); setlength(tBinNames, 0); raise exception.Create('error BinCodes'); end; for i := 0 to rslt - 1 do begin if TraysName = tBinNames then begin Result := BinCodes; Break; end; end; finally setlength(BinCodes, 0); setlength(tBinNames, 0); end; end; end; |
