.net – Feed paper on POS Printer C#

netpoint-of-saleprinting

I've been trying to programatically feed the paper on a pos printer (Epson TM-U220D). The problem I have is that the last line of the document don't get printed, instead, it is printed as the first line of the next document printed. I tried POS for .NET sending the "ESC|flF" command, also tried to send the raw esc/pos command using the serial port, but it doesn't work. Any ideas?

You will need sooner or later the full ESC/POS Application Programming Guide. I did obtained a copy from my EPSON dealer some years ago. In the meantime, I have found with Google a link to the FAQ for ESC/POS here: https://web.archive.org/web/20111229102746/http://postechgroup.com/updata/support/drivers/EPSON/FAQ_ESCPOS.pdf

In your case, the LF control command prints the data in the print buffer and feeds one line based on the current line spacing.

ASCII: LF

Hex: 0A

Decimal: 10

Your cut command is send out wrong.

The GSv0 is split into: GS (group seperator) #29 v that is the lower case 'v' 0 the binary value zero #0

This should make the cut.

Thank you very much Hans. Now I can send Paper cut command by using Microsoft RawPrinterHelper class. I've been seeking this solution for six days. Here is what I've done.

string GS = Convert.ToString((char)29);
string ESC = Convert.ToString((char)27);

string COMMAND = "";
COMMAND = ESC + "@";
COMMAND += GS + "V" + (char)1;

PrintDialog pd = new PrintDialog();
pd.PrinterSettings = new PrinterSettings();
if (DialogResult.OK == pd.ShowDialog(this))
{
RawPrinterHelper.SendStringToPrinter(pd.PrinterSettings.PrinterName,  COMMAND);
}
