Features & Capabilities

The web application embeds a print button — in Koha, notice/slip templates carry it:

html
   &lt;button id="webPrint" data-printer="receipt_printer" data-print="#receipt">Print&lt;/button>

data-printer names one of five logical printers — receipt_printer, sticker_printer, paper_printer, full_sheet_printer, label_printer — and data-print is a CSS selector for the element whose contents should print. Any element with the olorinPlugin class works the same way.

Wrap the printable part of the slip:

html
   &lt;span id="receipt"> ... slip content ... &lt;/span>

To print automatically when the page loads, trigger a click on the button from the page's own JavaScript. In Koha that means setting the IntranetSlipPrinterJS system preference to:

javascript
   setTimeout(function () {
     $("#webPrint").trigger("click");
   }, 1000);

(Any page script that dispatches a real click works — jQuery is not required.)

The extension's options page maps each logical printer to a real OS printer, with per-printer page size, margins, orientation, number of copies, and duplex (long edge / short edge) mode. Settings are stored by the companion app, so they are shared by every browser on the machine.

Pages can react to print outcomes by listening for a DOM event:

document.addEventListener("olorin:print-result", (e) => console.log(e.detail)); // e.detail = { success: true } or { success: false, error: "..." }

Is Olorin Auto-Printer Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Olorin Auto-Printer requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Olorin Auto-Printer is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
