I've googled and found some interesting answer, also i'm trying to apply those in my project but nothing makes me happy.
I'm using CITIZEN CT-S310 thermal printer and found this following printer commands from its website:
[Function] Full cutting of paper
[Code] <1B>H<69>H
[Outline] [Thespecificationwhichiscommontothemodel]
• Executes full cutting of paper.
[Caution] [Thespecificationwhichiscommontothemodel]
• This command onlyworks it is entered at the beginning of a line.
• Before cutting paper, feed the papermore than the cutting position of paper fromthe print position.Without
this paper feeding, the character just after printing remains before the cutter.
MSW4-8=ON:This commandworks as partial cut command.
But i am unable to implement this page cut command. Though i'm using
RawPrinterHelper [
^].
code snippet:
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
if (DialogResult.OK == ofd.ShowDialog(this))
{
PrintDialog pd = new PrintDialog();
pd.PrinterSettings = new PrinterSettings();
if (DialogResult.OK == pd.ShowDialog(this))
{
string output = Convert.ToChar(6) + "F" + "P";
RawPrinterHelper.SendStringToPrinter(pd.PrinterSettings.PrinterName, output);
RawPrinterHelper.SendFileToPrinter(pd.PrinterSettings.PrinterName, ofd.FileName);
}
}
}

Please help me to solve this.
Thanks in advance.
