WinDev LPR (DOS) Function
March 30, 2021 04:39PM

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 ?

Thanks in advance
