I think it may only be possible if the printer is capable of accepting a specific command to backfeed. There's no printer object method to do this.

It's worthwhile checking a few things first before trying to send a specific "backfeed" command string.

1. I have used DM printers where they automatically feed on to allow you to tear off the print - check the printer settings via the machines control panel/DIP switches.

2. Have you made sure that the form length of the printer (via its DIP switches) matches the Windows printer driver form length? It depends whether a form feed character is sent to the printer, or whether the printer driver moves to the end of the form by counting line feeds. Often you can get a conflict whereby the printer formfeeds and so does the driver.

3. Has the printer driver got any specific intialisation strings that it sends. If so, check that they are for the correct printer (are you in fact using the correct Windows printer driver?)

4. >For every print out Dot matrix printer leaves two lines<. Just in case you mean "every line" then check that the printer is NOT doing CR/LF for each LF or CR it receives. 'Cos for a CR/LF that you send from the program you'd get TWO CR/LF's on the printer.

5. If you have to send a specific character string do this:

Printer.Print Chr$(33) & Chr$(..) & Chr$(..) & ....

Where 33 is ESCape and normally begins a control sequence and .. are the specific codes required.

Sorry, that should of course be Chr$(27) for ESCape! (33 octal is 27 decimal)
