XML2ESCPOS 0.6.0

XML2ESCPOS

Net Standard library that provides a simple XML Template engine with support for images, variables and loops. For ESC / POS Thermal Printers. You can print to Windows printers (using the print queue so windows takes care of waiting for it to turn on or have paper) or directly to network printers.

Example:

XML2ESCPOS.Engine xML2ESCPOS = new XML2ESCPOS.Engine
{
     Template = "<C><RESET/><CENTER/>Hello!<BR><BR><END/></C>",
     PrinterName = "Epson"
};
xML2ESCPOS.Print();

Printer print:

                   Hello!

Engine Properties:

PrinterName: Windows Printer Name. When PrinterName is set, PrinterIP is disabled

PrinterIP: Printer IP Address. When PrinterIP is set, PrinterName is disabled

Plantilla: String with the Template

PrintJobName: (Default is "PrintJob") Print job name

CodePage: (Default is 858) Codepage that has the thermal printer configured. https://docs.microsoft.com/en-us/windows/win32/intl/code-page-identifiers

Vars: (List<KeyValuePair<string, string>>) List of the variables that you are going to use with their name and value. More Info

BubleVars: (List<KeyValuePair<string, string>>) List of variables that are the lists that you will use with each loop with its name More Info

            Template = plantilla,
            PrinterName = "Epson"
        };

xML2ESCPOS.Vars.Add(new KeyValuePair<string, string>("MyName", "Jesus"));
xML2ESCPOS.Vars.Add(new KeyValuePair<string, string>("YourName", "  "));

xML2ESCPOS.Print();

Printer Print:

xML2ESCPOS.Vars.Add(new KeyValuePair<string, string>("MyName", "Jesus"));
xML2ESCPOS.Print();

Example:

public class Client
{
    public string Name { get; set; }
