请问，怎样可以将打印机打印出来的内容记录到一个档案中？

記得大多數的印表機都有列印到檔案的功能，你可以在列印設定或印表機設定中找找。

type
TPrinterInfo = record
SeverName : PChar;
PrinterName : PChar;
ShareName : PChar;
PortName : PChar;
DriverName : PChar;
Comment : PChar;
Location : PChar;
DeviceMode : PDeviceModeA;
SepFile : PChar;
PrintProcessor : PChar;
DataType : PChar;
Parameters : PChar;
SecurityDescriptor: PSecurityDescriptor;
Attributes : Cardinal;
DefaultPriority : Cardinal;
StartTime : Cardinal;
UntilTime : Cardinal;
Status : Cardinal;
Jobs : Cardinal;
AveragePPM : Cardinal;
end;
function GetCurrentPrinterInformation: TPrinterInfo;
var
hPrinter : THandle;
pInfo: PPrinterInfo2;
bytesNeeded: DWORD;
begin
hprinter := GetCurrentPrinterHandle;
try
Winspool.GetPrinter( hPrinter, 2, Nil, 0, @bytesNeeded );
pInfo := AllocMem( bytesNeeded );
try
Winspool.GetPrinter( hPrinter, 2, pInfo, bytesNeeded, @bytesNeeded );
Result.SeverName := pInfo^.pServerName;
Result.PrinterName := pInfo^.pPrinterName;
Result.ShareName := pInfo^.pShareName;
Result.PortName := pInfo^.pPortName;
Result.DriverName := pInfo^.pDriverName;
Result.Comment := pInfo^.pComment;
Result.Location := pInfo^.pLocation;
Result.DeviceMode := pInfo^.pDevMode;
Result.SepFile := pInfo^.pSepFile;
Result.PrintProcessor := pInfo^.pPrintProcessor;
Result.DataType := pInfo^.pDatatype;
Result.Parameters := pInfo^.pParameters;
Result.SecurityDescriptor := pInfo^.pSecurityDescriptor;
Result.Attributes := pInfo^.Attributes;
Result.DefaultPriority := pInfo^.DefaultPriority;
Result.StartTime := pInfo^.StartTime;
Result.UntilTime := pInfo^.UntilTime;
Result.Status := pInfo^.Status;
Result.Jobs := pInfo^.cJobs;
Result.AveragePPM := pInfo^.AveragePPM;
finally
FreeMem( pInfo );
end;
finally
ClosePrinter( hPrinter );
end;
end;
