Badge printing happens automatically after a QR code is scanned in the Service app — from the scan to the printed badge it is under one second, and the hostess peels off the badge and sticks it onto the lanyard. The supported printer is the Brother QL-820NWB thermal printer, paired with the phone or tablet over Bluetooth. The data on each badge is pulled from the attendee's contact details in Contacts and groups. If you do not own a printer, Happenee rents one out at the current rate — arrange this 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 pricing with customer success.
On event day, test in advance — the Bluetooth pairing, the badge size set on the printer, and the print quality.
The attendee reaches the entrance, the hostess scans the QR code in the Service app on a phone or tablet. The Service app is paired over Bluetooth with the Brother QL-820NWB thermal printer, and within roughly one second a badge is printed. The hostess peels the badge off and sticks it onto the lanyard the attendee is wearing.
This is the standard recommended model. It prints thermally — no ink needed, just a roll of badges in the right size. Pairing runs through Bluetooth from the Service app. One printer is paired with one phone or tablet at a time.
If you do not own a printer, 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 on the badge for Networking.
Small badge (70 × 29 mm) — fits first name, last name, and possibly one extra field. A QR code does not fit on it — 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 stored in Contacts and groups. If an attendee filled in Company on the Registration form but you set the badge to print Job title, that field stays blank. Confirm in advance that attendees actually 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 and start a conversation. If you are not using that feature, a QR on the badge has no purpose.
The QR code can only be printed on the large badge (80 × 50 mm). For the scanning mechanics, see How Networking works.
In the Check-in web tool you can quickly add a new attendee (at minimum first and last name) and then scan them in the Service app — that triggers the badge print. Useful when someone arrives unregistered and you need to check them in on the spot. Details in How check-in and QR-code scanning work.
The most common cause is the wrong badge size set inside the printer. The printer keeps its own media-size configuration, and it has to match the roll you have loaded (80 × 50 or 70 × 29). Before the event, test by hand — load the roll, set the size, print a test badge.
Check the Bluetooth pairing between the tablet or phone and the printer. When you switch operators (a different phone), the pairing is lost — you have to re-pair.
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 actually 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 — both for redundancy and for 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.
