You can print a badge in the Service app two ways: automatically after a QR code is scanned (from the scan to the finished badge it is under one second), or on demand from a button — Print badge on the attendee detail, or by swiping a row in the list (the Print badge action). In Kiosk mode the badge prints by itself after a self-service check-in. Printing runs on a Brother QL-820NWB thermal printer paired with the phone or tablet over Bluetooth. The data is pulled from the attendee's contact details in Contacts and groups. If you do not own a printer, Happenee rents one out — arrange it in time through customer success.
Decide which badge size you will use: large 80 × 50 mm (allows a QR code) or small 70 × 29 mm (no QR).
Decide what goes on the badge alongside first and last name: company, job title, a note — or nothing.
Decide whether to print a QR code on the badge — worth it if you plan to use the Attendees engagement feature in the attendee app (QR scanning for Networking).
If you are renting the printer from Happenee, agree on the delivery date and payment with customer success.
Test the day before — the Bluetooth pairing, the badge size set on the printer, and the print quality. The Service app has a Print test badge button for this in Settings.
After a QR scan in Staff mode — staff scan the QR and, with a paired printer, the app offers to print.
On demand from the attendee detail — the Print badge button. Use it to print (or reprint) without a scan.
By swiping a row in the list — the Print badge action prints straight from the Attendees list.
In Kiosk mode — the badge prints automatically after a self-service check-in.
Staff peel the badge off and stick it onto the lanyard the attendee is wearing.
You pair the printer in the app: in Settings, open Connect badge printer (or the Printer row on the event's start screen), put the printer into pairing mode, and tap Pair new printer. When it appears in the list, select it and confirm. If pairing does not work, the app points you to the manual route through Settings → Bluetooth on the device.
One printer is paired with one phone or tablet. Switching to a different device drops the pairing, so you have to re-pair.
The standard recommended model. It prints thermally — no ink, just a roll of badges in the right size. If you do not own one, Happenee rents one out at the current rate. The agreement and the details (delivery, deposit, return) go through customer success — plan with lead time.
Two standard sizes:
Large badge (80 × 50 mm) — fits first name, last name, an extra field, and a QR code. Use it when you want a QR for Networking.
Small badge (70 × 29 mm) — fits first name, last name, and possibly one extra field. A QR code does not fit — physically too small.
The badge size must be set correctly inside the printer — see Common pitfalls.
The badge always prints first and last name (required). On top of that you pick one extra field:
Company — fits B2B events, client events, conferences.
Job title — fits professional conferences, networking nights.
Note — a free-text field on the attendee profile (typically dietary info, role, dress code).
None — first and last name only.
The data is pulled from the contact details in Contacts and groups. If an attendee filled in Company but you set the badge to print Job title, that field stays blank. Confirm in advance that attendees filled in what you plan to print.
Only when you plan to turn on the Attendees engagement feature in the attendee app (Networking with QR scanning). Attendees scan each other's QR codes from the badges to save the contact. If you do not use that feature, a QR on the badge has no purpose. A QR can only be printed on the large badge (80 × 50 mm). For the mechanics, see How Networking works.
When a walk-in arrives, register them right in the Service app with Add attendee (on the Attendees list) and then print their badge with Print badge. The same is possible in the web Check-in tool. Details in How check-in and QR-code scanning work.
The most common cause is the wrong media size set inside the printer. The printer keeps its own size configuration, which has to match the loaded roll (80 × 50 or 70 × 29). Before the event, test by hand — load the roll, set the size, and use Print test badge in the app's Settings.
Check the Bluetooth pairing between the device and the printer. Switching operators (a different phone) drops the pairing — re-pair through Pair new printer, or via Settings → Bluetooth on the device.
The data comes from the contacts. If attendees did not fill in Company (or it was not a field on the Registration form), the system has nothing to print. Make sure the field exists on the form and that attendees filled it in.
Not possible — the QR does not physically fit. If you need a QR, use the large badge (80 × 50 mm).
Keep a backup printer and a backup roll of badges. For larger events, two print stations are worth it — for redundancy and higher throughput.
The rental through customer success is not instant — there is logistics, a deposit, and a return. Order at least 10 days in advance.
