Features

ReceiptIO is a simple print application for receipt printers that prints with easy markdown data for receipts and returns printer status. Even without a printer, it can output images.

A development tool is provided to edit and preview the receipt markdown.
https://receiptline.github.io/designer/

The details of the receipt markdown are explained at
https://github.com/receiptline/receiptline

Receipt Printers

Epson TM series
Seiko Instruments RP series
Star MC series
Citizen CT series
Fujitsu FP series

Connect with IP address, serial port, or Linux USB device file.
(LAN, Bluetooth SPP, USB with virtual serial port driver, ...)

Epson TM series (South Asia model) and Star MC series (StarPRNT model) can print with device font of Thai characters.

Installation

$ npm install -g receiptio

For USB connections on Linux, add a user to the lp group and reboot to access the device file.

$ sudo gpasswd -a USER lp

If serial port is used, Node SerialPort is also required.

$ npm install -g serialport

When using -i (print as image) or -p png (convert to png) option, puppeteer or sharp is also required.

$ npm install -g puppeteer

$ npm install -g sharp

sharp is not support web fonts and minimizes the area of "invert" character decoration.
