How can I send text file to printer port?

Again,

take the text in your batch file and place it between the "" in the following line and send it to the system exec as a string

cmd /C ""

My text file includes printer commands. Do u think that problem related with them. Batch file converts my printer commands in the textfile  to graphic. I want to sent these printer command my printer port to see again graphic. When I use batch file, I used to copy command like copy c:\plot.txt lpt2    This shows graphic. Then I try without batch. I wrote cmd/c "copy c:\plot.txt >lpt2".    I said again that  saw only 1file(s) copied.

Maybe it's a language difference problem, but I'll repeat for the third time....

Use the SAME text in your system exec command string as in your batch file, but place it inside the "" int he following line

Cmd /C ""

Thus, if you say copy c:\plot.txt lpt2 works then please try Cmd /C "copy c:\plot.txt lpt2"

Can you please post the part of your vi that does this print?  And a copy of the text file?

filozof,

I got it figured out and was able to get your file to print on my printer here. 

First your "text file" is NOT a text file.  Your file is the output of a "print/plot to file" operation.  It must be copied to the printer port.

I've attached an LV 8.2 copy of my vi.  Maybe some kind soul monitoring this can convert it to LV 7.1 for you.  I'll also include an image of the block diagram.  Please note that I have used the "Working Directory" input.  This will not work if you try to include the path in the copy command.
