DemoPOS

DemoPOS is a simple and lightweight fluent wrapper around RawPrint and ESCPOS to allow for simple and direct printing to a thermal printer installed on a windows machine (Such as an Epson TM-T88IV for example).

The usage is quite straightforward:

To get a list of names of installed printers on the machine, use the RegistryHelper class:

var printers = RegistryHelper.GetInstalledPrinterNames();

Then, create a new DocumentManager with the desired ESC/POS Printer of your choice:

var manager = new DocumentManager(PrinterName);

You can then chain various commands via a fluent style api, such as:

manager.AddTitle("Hello World") .AddLine("This is a test print") .AddLine("On a thermal printer.") .AddQrCode("http://www.example.com") .AddEmptyLines(5) .Cut();

To send the commands to the printer, either use the print command (this will clear the command buffer)

manager.Print();

or use the PrintAndContinue command, to keep the buffer (for repetitive printing of the same receipt, for example)

manager.PrintAndContinue();

If you have any issues with this package, or would like more features (commands) added to the DocumentManager, feel free to open a feature or a pull request on this repository!
