Hello My solution will not work: For a exotic Labelprinter I have to send Binary data direct to the printer. I do this creating a File with the data. Then I create a DOS Batch file as follow: Cmd is string = "c:\windows\system32\LPR.exe -S " + Computername + " -P " + Printername + " " + Filename + " -ol" an write it to my disk: fSaveText("C:\Temp\Batch.bat", Cmd) This Batch can I start manualy without any problems, it works. But unfortunately I am not able to start the batch by WinDev I tryed 'exerun', 'DDEstart' (DDEStart("C:\Temp\Batch.bat")) whatever i try, it does'nt work Anybody can help me ?
