Features

The reference implementation of the OFSC ReceiptLine Specification.
http://www.ofsc.or.jp/receiptline/en/

ReceiptLine is the receipt description language that expresses the output image of small roll paper.
It supports printing paper receipts using a receipt printer and displaying electronic receipts on a POS system or smartphone.
It can be described simply with receipt markdown text data that does not depend on the paper width.

This reference implementation also provides the development tool "ReceiptLine Designer" for editing, previewing, hex dumps with a virtual printer, and test printing on receipt printers.

Receipt Printers

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

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

Printers

const destination = fs.createWriteStream('example.svg');

source.pipe(transform).pipe(destination);

Method

receiptline.createTransform([printer])

Parameters

Grammar

Structure

The receipt is made of a table, which separates each column with a pipe |.

|Line|Content|Description| |---|---|---| |column| column || columncolumn ||TextProperty|Single column| |column | column | column | column || column | columncolumn | column ||Text|Double column| |column | ... | column| column | ... | column || column | ... | columncolumn | ... | column ||Text|Multiple columns|

Alignment

The column is attracted to the pipe | like a magnet.
␣ means one or more whitespaces.

|Column|Description| |---|---| |column|column||␣column␣||Center| ||column|column␣|column␣||Left| |column||␣column||␣column|Right|

Text

The text is valid for any column.

Asparagus | 0.99
Broccoli | 1.99
Carrot | 2.99
---
^TOTAL | ^5.97

Characters are printed in a monospace font (12 x 24 px).
Wide characters are twice as wide as Latin characters (24 x 24 px).
Control characters are ignored.

Special characters in text

Special characters are assigned to characters that are rarely used in the receipt.

|Special character|Description| |---|---| |\|Character escape| |||Column delimiter| |{|Property delimiter (Start)| |}|Property delimiter (End)| |- (1 or more, exclusive)|Horizontal rule| |= (1 or more, exclusive)|Paper cut| |~|Space| |_|Underline| |"|Emphasis| |`|Invert| |^|Double width| |^^|Double height| |^^^|2x size| |^^^^|3x size| |^^^^^|4x size| |^^^^^^|5x size| |^^^^^^^ (7 or more)|6x size|

Properties

The property is valid for lines with a single column.

{ width: * 10; comment: the column width is specified in characters }

Barcode options

Barcode options are separated by commas or one or more whitespaces.

|Barcode option|Description| |---|---| |upc|UPC-A, UPC-E(Check digit can be omitted)| |eanjan|EAN-13, EAN-8(Check digit can be omitted)| |code39|CODE39| |itf|Interleaved 2 of 5| |codabarnw7|Codabar (NW-7)| |code93|CODE93| |code128|CODE128| |2 - 4|Barcode module width (px)| |24 - 240|Barcode module height (px)| |hri|With human readable interpretation| |nohri|Without human readable interpretation|

2D code options

2D code options are separated by commas or one or more whitespaces.

|2D code option|Description| |---|---| |qrcode|QR Code| |3 - 8|Cell size (px)| |lmqh|Error correction level|

Special characters in property values

Special characters in property values are different from special characters in text.

|Special character|Description| |---|---| |\|Character escape| |||Column delimiter| |{|Property delimiter (Start)| |}|Property delimiter (End)| |:|Key-value separator| |;|Key-value delimiter|

Escape sequences in property values

Escape special characters.

|Escape sequence|Description| |---|---| |\\|\| |\|||| |\{|{| |\}|}| |\;|;| |\n|New line| |\xnn|Hexadecimal character code| |\char (Others)|Ignore|

Restrictions

Communication with the printer, status event processing, and error handling are out of scope.
SVG images depend on the font family installed on the computer and may not display properly.
Impact printer has some limitations for printing.
- Characters larger than 2x size
- Inverted characters (will be printed in red)
- Double height characters in different colors on the same line
- Multibyte characters
- Image position and size ratio
- Barcodes and 2D codes
Star Graphic Mode printing only supports images, line feeds, and paper cuts.
sharp is not support web fonts and minimizes the area of "invert" character decoration.
