Depends on how you want to see it. Simplest would be to just take the report.txt file, open it, line input it, then dump it into a textbox. Of course, there's the whole size limit thing to worry about.

Next possibility is to have a "Preview" button that creates the text file, then instead of your REPO.BAT file using "TYPE report.txt > PRN", you could just use "TYPE report.txt | MORE". This will display the output to the console and pause when the screen fills. If they don't want to go through the entire file, they can use the <ctrl>-<c> keystroke combination to abort.

Hope this helps! Good luck!

I don't really think that shelling out to a batch file is particularly good. It might be better to write to the printer directly yourself. you can open it as follows

open PRN for output as #2

As far as previewing, why don't you load the lines from the file into a list box then your user could scroll up and down through the report.
