+The receipt submodule provides for receipt printing. It depends on the jQuery plugin receipt-print.
+
+### Install using Composer (recommended)
+
+If you use Composer to manage dependencies, edit `/composer.json` as follows.
+
+1\. Run `composer require --prefer-dist composer/installers` to ensure that you have the `composer/installers` package installed. This package facilitates the installation of packages into directories other than `/vendor` (e.g. `/libraries`) using Composer.
+
+2\. Add the following to the "installer-paths" section of `composer.json`:
+
+```
+"libraries/{$name}": ["type:drupal-library"],
+```
+
+3\. Add the following to the "repositories" section of `composer.json`:
+
+```
+"jQuery.print": {
+    "type": "package",
+    "package": {
+        "name": "DoersGuild/jQuery.print",
+        "version": "1.5.1",
+        "type": "drupal-library",
+        "dist": {
+            "url": "https://github.com/DoersGuild/jQuery.print/archive/1.5.1.zip",
+            "type": "zip"
+        }
+    }
+},
+```
+4\. Run `composer require --prefer-dist DoersGuild/jQuery.print:1.5.*` - you should find that a new directory created
+under `/libraries`
+
+### Install manually
+
+  - Create a `/libraries/jQuery.print/` directory below your Drupal root directory
+  - Download https://raw.githubusercontent.com/DoersGuild/jQuery.print/1.5.1/jQuery.print.js
+  - Rename it to `/libraries/jQuery.print/jQuery.print.js`
+
+  For further details on how to obtain jQuery.print.js, see https://github.com/DoersGuild/jQuery.print
