Need help with displaying chars starting from line1 position 1

Question

Hi,

I am using an HP RS232 pole display with setting as listed below. Also the documentation is provided in this link: http://www.camax.it/manuali/Manuale%20LD220%20VFD.pdf

• Char type: USA/Europe (default)
• Command mode: EPSON (default)
• Baud rate: 9600, n , 8, 1 (default)
• Passthru None (Default)

Here's the code

using System.IO.Ports;

private SerialPort port;
port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One);
port.Handshake = Handshake.None;

Port.WriteLine("Welocome to something something");

It has 2 lines consisting of 20 characters each with a total of 40 characters. I have no control how and where the characters get displayed. I would like it to always begin on line 1 position 1 but as I said earlier how would I be able to do that. The same program if I run again and again it moves a character to the left. I have set it to accept ASCII char set and so I am able to type as is visble in the Writeline message. But I could set it as Hex if needed

I think you will have to somehow communicate to the printer's device driver library to have it always begin on line 1 position 1;

Try epsonexpert.com for EPSON device driver library for .NET. Also this and this discussion might help.
