Smaller Font size for POSPrinter PrintNoraml on Slip

Question

Smaller Font size for POSPrinter PrintNoraml on Slip

Raj B 0

I am using

POS for .NET 1.14.1 SDK and EPSON OPOS ADK for .NET Ver.1.14.20E

I am unable to make Font size smaller while printing on Slip using : TM-H6000V (EPSON Printer)

I am using following code to print on slip

_posPrinter.PrintNormal(PrinterStation.Slip, printtext);

I need to make font size small when it prints on slip

Also I am not able to find any documentation which help all different formatting instruction like this

Normal = sCEsc + '|N';

Bold = sCEsc + '|bC';

@Raj B, Welcome to Microsoft Q&A, you could try the following code to set small font size:

 // Set font size to small
        byte[] cmd = new byte[] { 27, 33, 1 };
        printer.PrintNormal(PrinterStation.Receipt, Encoding.ASCII.GetString(cmd));

        // Print text
        string text = "Small Text";
        printer.PrintNormal(PrinterStation.Receipt, text);

Also, you could try to change the byte array to set your format:

         // Set bold text
        byte[] cmd2 = new byte[] { 27, 69, 1 };
        printer.PrintNormal(PrinterStation.Receipt, Encoding.ASCII.GetString(cmd2));

Thank you @Jack J Jun

This did not solve the problem. It actually prints the character like ft on the slip?

Should i do it like following?

 byte[] cmd = new byte[] { 27, 33, 1 };
                 
_posPrinter.PrintNormal(PrinterStation.Slip, Encoding.ASCII.GetString(cmd));

_posPrinter.PrintNormal(PrinterStation.Slip, printLine.Text );

Or should do i need to do it like following


_posPrinter.PrintNormal(PrinterStation.Slip, Encoding.ASCII.GetString(cmd) + printLine.Text  );

@Raj B, thanks for the feedback, please check if the following code works for you:

byte[] cmd = new byte[] { 27, 33, 0 }; _
posPrinter.PrintNormal(PrinterStation.Slip, Encoding.ASCII.GetString(cmd)); _posPrinter.PrintNormal(PrinterStation.Slip, "Text to print in small font size.");
