Nodeprinter is a simple nodejs rest api that uses a fork of the node-printer repo and combines them with node-thermal-printer the way it works is that you can send commands to the localhost:1337/printer-data in an object as follows { printerName: string; printerCommands: string[] }
effortless example:
let printerData = {
printerName: "nodePrinter",
printerCommands: [
"printer.newLine()",
"printer.newLine()",
"printer.alignLeft()",
printer.println('Fecha: ${format( fromUnixTime(sale.createdAt), "dd/MM/yy HH:mm" )}'),
"printer.newLine()",
printer.println('Cliente: ${ sale.customer ? sale.customer.razonYRuc : "Sin nombre" }'),
printer.println('Forma de pago: ${paymentTypeName( sale.paymentType )}'),
"printer.alignLeft()",
...productsList,
"printer.alignCenter()",
"printer.newLine()",
printer.println('Total: ${sale.total}'),
"printer.newLine()",
"printer.newLine()",
"printer.newLine()",
"printer.drawLine()",
"printer.newLine()",
"printer.newLine()",
],
};
