QR Codes
Print QR code asset tags for your inventory items. A staff member scans a tag with any phone and lands straight on that item’s record, with no searching and no typing.
This is built for the moment a customer asks about an item and your team is standing next to the stock rather than a computer.
What you need
– WP Inventory Manager Pro with an active licence
– PHP 8.1 or higher
– The QR Codes add-on, installed and activated
Installing the add-on
1. Download the add-on from your account on wpinventory.com.
2. In WordPress, go to Plugins, then Add New, then Upload Plugin.
3. Choose the zip file and click Install Now, then Activate.
4. If prompted, enter your licence key.
Once activated you will see a QR Codes page under the WP Inventory menu.
Printing tags
Add your inventory items first. Tags are generated from items that already
exist, so a tag always points at a real record.
Go to WP Inventory, then QR Codes, and choose how you want to print:
– Single item. Enter one item ID.
– Multiple items. Enter several IDs separated by commas, for example `1,2,3`.
– Range of items. Enter a starting and ending ID to tag a whole batch. Any IDs in the range that do not have an item are skipped, so you never get a blank tag.
Then set your options:
- How many would you like to print: copies of each label
- Width of the QR Code: size of the code in pixels
- Margin: white space around the code, in pixels
Click Print, then use your browser’s print dialog.
Printing a tag for one item
You can also print from the item itself. Open any inventory item, scroll to the QR Code section, and click Print Code.
What is on a tag
Each tag shows the QR code with the item’s name and number underneath, so your team can identify a tag at a glance without scanning it.
What happens when a tag is scanned
Scanning opens that item’s record in the WordPress admin, where staff can check details and make changes.
Because it opens the admin, the person scanning needs to be signed in to your site on that device. If they are not signed in, WordPress asks them to log in first and then takes them straight to the item. Signing in once per device is usually enough.
Choosing who can print codes
On the QR Codes settings you can set Minimum Role to Use QR Codes. This is the lowest role allowed to generate and print codes. It defaults to Administrator.
Tips for good tags
– Print one sheet first and check it scans before running a large batch.
– Keep some margin. Scanners need white space around a code to read it reliably.
– The codes are vector, so they stay sharp at any size. You can print small tags without them turning fuzzy.
– If you are sticking tags on small items, reduce the width rather than shrinking the printed page.
Troubleshooting
“QR Codes does not appear in the WP Inventory menu.”
The add-on needs WP Inventory Manager Pro with a valid licence. Check your licence key under WP Inventory settings.
“Scanning a tag asks me to sign in.”
That is expected. Tags open the item in the WordPress admin, so the device needs to be signed in. Log in once and the scan will take you to the item.
“Some items in my range did not print.”
IDs in the range that do not have an inventory item are skipped on purpose, so you do not end up with tags that lead nowhere.
“The plugin will not activate.”
The add-on requires PHP 8.1 or higher. Ask your host to update PHP if you are on an older version.
