VB.NET 7, printing to a printer directly

[Marc Champagne]

Hi folks,

I wish to print on pre-printed continuous forms on a dot
matrix printer.

My initial intent was to access to printer directly (in raw
mode, somehow) in order to send whatever is necessary to do
the job.

I had to try... but FileOpen does not permit opening LPT1.

From what I gatter (I may understand this incorrectly) the
printdocument component seems to be a graphical approach at
printing on modern cut-sheet printers (laser, inkjet).

The only aspects of printing I need are to send appropriate
text, CR/LFs, formfeeds and CPI settings all the while using
the printer's default power-on font.


Alternatively, I have a back door, but it's not elegant.

1) Create a textfile.txt via VB with the appropriate
print data.

2) Shell("printit.bat", AppWinStyle.Hide)

3) printit.bat contains: copy /b textfile.txt lpt1:


Any help to get me on the right track here would be more than
welcomed.

Thanks

Marc,
Take a look at this article
http://www.c-sharpcorner.com/Code/2002/Oct/PrintDirect.asp for information
on printing directly to the printer. You should be able to adapt this to
VB.NET.
