Share standard printers via JSON API
Clone repository:
git clone [email protected]:yevgenko/printer-express.git
Install dependencies:
cd printer-express
npm i
Run the server (default port is 3000, but can be adjusted via environment variable PORT):
node standalone.js
Install printer-express package with npm:
npm i printer-express --save
Use middleware with Express application:
var express = require('express'),
printerExpress = require('printer-express'),
app = express(),
port = process.env.PORT || 3000;
// mount point for JSON API, i.e. /cloudprint/printers and /cloudprint/jobs
app.use('/cloudprint', printerExpress);
app.listen(port);
Get the list of printers installed on the hosting system:
curl -v http://localhost:3000/printers
or with jQuery:
$.getJSON("http://localhost:3000/printers");
Submit new printing job:
curl -v -X POST http://localhost:3000/jobs -H "Content-Type: application/json" -d '{"data":"Hello, World!", "type":"RAW", "printer":"stkPrinter"}'
or with jQuery:
$.ajax({
type: 'POST',
url: "http://localhost:3000/jobs",
data: JSON.stringify({data: 'Hello, World!', type: 'RAW', printer: 'stkPrinter'}),
dataType: 'json',
contentType: "application/json; charset=utf-8"
});
To print from file, i.e. PDF, simply replace data and type attributes with
url pointing to the publicly accessible file, for example:
curl -v -X POST http://localhost:3000/jobs -H "Content-Type: application/json" -d '{"url":"http://example.com/print.pdf", "printer":"stkPrinter"}'
We can also omit the printer attribute, in which case system default printer
will be used.
