Label Printer Fonts

Introduction

The label to be printed for each Job is specified in the ticket.json sent from the external system. The description is then processed into a PDF file which is sent to the printer.

Therefore, all PDF standard fonts are available for printing:

• Courier, Courier-Bold, Courier-BoldOblique, Courier-Oblique
• Helvetica, Helvetica-Bold, Helvetica-BoldOblique, Helvetica-Oblique
• Symbol
• Times-Bold, Times-BoldItalic, Times-Italic, Times-Roman
• ZapfDingbats

However:

We do not recommend using a PDF standard font because they do not provide good printing qualtiy and they only support a limited set of international characters.

For best printing results, the RX400 comes with a high quality multilingual font set preinstalled, which should be used for label printing.

Label Specification with Preinstalled Fonts

In order to use one of the preinstalled fonts:

1. Add a sources block named fonts, referencing the fonts directory: /data/storage/jobs/. Please mind the trailing slash.
2. In label blocks of type text specify the font with a file specification:
   
   • "sourcename": "fonts"
   • "path": the font filename

{
  "version": "5.0",
  "sources": [
    {
      "type": ... Your type ...,
      "name": ... Your  source name ...,
      "path": ... Your path ...
    },
    {
      "type": "local",
      "name": "fonts",
      "path": "/fonts/"
    }
  ],
  "job": {
    "type": "write",
    "values": {
      ... Your values here ...
    },
    "settings": {
      "verify": "no",
      "verify_amount": 0,
      "verify_each": 1,
      "quantity": 1,
      "store": false,
      "autostart": true
    },
    "targets": [
      {
        "type": "usb",
        "data_type": "create",
        "devicename": ... Your filesystem label ...,
        "filesystem": "exfat",
        "data": [
          {
            "sourcename": ... Your source name ...,
            "mapping": {
              "path": ... Your path ...,
              "destination": "/"
            }
          }
        ]
      }
    ],
    "label": {
      "type": "create",
      "size": { "width": 54, "height": 25 },
      "blocks": [
        ... Your blocks here ...
        Two example text lines with recommended fonts follow:
        {
          "type": "text",
          "align": "left",
          "position": { "x": 1, "y": 18 },
          "text": {
            "color": "#000000",
            "font_size": 9,
            "lines": [ "Title line - NotoSansDisplay-Bold 9" ],
            "file": {
	          "sourcename": "fonts",
	          "path": "NotoSansDisplay-Bold.ttf"
	        }
          },
	      {
            "type": "text",
            "align": "left",
            "position": { "x": 1, "y": 11 },
            "text": {
            "color": "#000000",
            "font_size": 8,
            "lines": [ "Text line - NotoSansDisplay-SemiBold 8" ],
            "file": {
	          "sourcename": "fonts",
	          "path": "NotoSansDisplay-SemiBold.ttf"
	        }
          }
        ]
      }
    }
  }
}
