Event Badge Printer Guide

Printer Guide

Which printer do you actually need?

The answer depends on your badge format, attendee count, and whether colour matters, and most event organisers only find out the hard way after ordering the wrong stock.

The 30-second answer

500+ attendees, name + QR only

Zebra ZD621 on thermal fanfold. Fastest throughput, lowest cost per badge, no ink to run out.

Full-colour variable data badges

Small adhesive visitor passes

Brother QL820 label printer. Peel-and-stick 62 mm roll, ideal for daily office visits or short-run events.

Thermal vs inkjet vs label: the real differences

These three technologies are not interchangeable. Choosing wrong means buying new stock on event day.

Zebra ZD621: Direct Thermal

Print method: Direct thermal (heat on paper)
Colour: Black only
Speed: High, suited to queues of 500+
Cost per badge: Lowest (no consumables beyond stock)
Media type: Thermal fanfold (4×3″ or 4×6″)
Best for: Conferences, expos, large-scale check-in
Limitations: No colour; thermal paper fades in direct sunlight over time

Epson WF-100: Portable Inkjet

Print method: Inkjet (CMYK cartridges)
Colour: Full colour
Speed: Moderate, suited to 50-300 attendees
Cost per badge: Moderate (ink + paper stock)
Media type: Cut-sheet inkjet badge paper or art card
Best for: VIP events, galas, branded colour badges
Limitations: Slower per badge; ink cartridges need monitoring

Brother QL820: Label Printer

Print method: Direct thermal on adhesive roll
Colour: Black only
Speed: Fast per label; roll capacity is the limit
Cost per badge: Low (roll stock is inexpensive)
Media type: 62 mm continuous adhesive roll
Best for: Short-run events, visitor passes, networking meetups
Limitations: Small format only; adhesive not suitable for all badge holders

Match your event to a printer

Pick your event type from the left column. Each row gives you a printer, a badge stock format, and the one-line reason why.

Corporate conference (200-500 attendees)

Zebra ZD621 + 4×3″ thermal fanfold

Fast enough for pre-registration queues; lanyard slot pre-cut; black-on-white is the professional standard.

Trade show or expo (500-2,000 attendees)

Zebra ZD621 (×2 stations recommended) + 4×6″ thermal fanfold

High throughput for large crowds at HKCEC or AsiaWorld-Expo; 4×6″ gives more space for session tracks and sponsor logos.

Gala or VIP event (100-300 attendees)

Epson WF-100 + A6 inkjet art card (260 gsm)

Full-colour badge matches premium branding; art card feels substantial; slower speed is fine at smaller scale.

Daily visitor pass (office / building lobby)

Brother QL820 + 62 mm continuous adhesive roll

Peel-and-stick in seconds; no badge holder needed; low daily volume suits the smaller roll capacity.

Multi-day festival with session badges

Zebra ZD621 + 4×6″ thermal fanfold

Large format accommodates colour-coded session tracks and QR codes for access control scanning.

What Cvent, Bizzabo, Accelevents, and Whova won't tell you

Every major check-in platform gives you a badge template editor. None of them ships you a printer. The software side (layouts, QR codes, data fields) is genuinely well handled by Cvent, Bizzabo, Accelevents, Whova, and the others. What they assume is that someone else has already sorted the hardware. That someone is usually you, one week before the event.

Platform documentation is written around generic "compatible printers" rather than specific models. That language hides a real constraint: the badge stock your printer accepts determines exactly which badge sizes you can offer. A Zebra ZD621 cannot print on inkjet art card. An Epson WF-100 cannot print on thermal fanfold. If you order the wrong stock, nothing works, and there is no fast fix at the venue.

"Event in a box" bundles, where a platform offers a starter kit, typically include the software licence, maybe a template, and sometimes a USB cable. Consumables (the actual paper or label rolls) are nearly always sold separately, often at inconvenient quantities. For a 600-person conference you may need three or four packs of fanfold; a starter kit usually comes with one.

None of this is a platform failing, it is simply outside their scope. Registration software companies are not in the hardware or consumables business. The practical result is that the printer choice, stock compatibility, and quantity planning fall to the event team, usually at the last minute. Knowing your printer before you finalise your badge template saves a round of redesign.

Rather not choose? We handle everything.

If you would prefer one call over a decision tree, TechRental.HK operates as a full-service badge printing crew. We assess your event, specify the right printer and stock, deliver and configure on-site, and staff the check-in desk from doors-open to doors-close. You tell us the guest count, the venue, and the date.

Frequently asked questions

What size badge should I order: 4×3 or 4×6?

4×3″ (102×76 mm) is the standard conference name badge, it sits in a lanyard holder comfortably and is readable at arm's length. Use 4×6″ (102×152 mm) when you need more content on the badge: session access codes, day indicators, QR codes for multiple scanning points, or sponsor logos. For visitor passes and small networking events, the 62 mm adhesive label from the Brother QL820 is usually sufficient. If you are unsure, 4×3″ is the safe default.

What is the lead time for custom-printed badges?

For on-demand printing (where badges are printed at check-in from your attendee list), there is no pre-print lead time: the printer produces each badge in seconds at the door. If you want pre-printed badges with fixed artwork on artcard or premium stock, allow 5-7 working days from artwork sign-off for production and delivery to your Hong Kong venue. Rush orders under 3 days are possible depending on quantity, ask when you request a quote.

Can I use my own existing Zebra printer?

Yes, and we can supply compatible badge stock for most Zebra models if you already own one. The critical detail is the print width: most event Zebra printers accept 4″ (102 mm) wide media. If your model accepts that, our fanfold packs will fit. Send us the model number and we will confirm compatibility before you order stock. We do also offer short-term printer rental if your hardware is in another office or needs servicing before the event.

What artwork format do you need?

For on-demand thermal printing the template is a ZPL (Zebra Programming Language) file or a ZDesigner / Bartender label file. Your check-in platform (Cvent, Bizzabo, Whova, etc.) generates this automatically from your badge design; you do not need to touch ZPL directly. For inkjet full-colour art card, supply a PDF at 300 dpi with 3 mm bleed, CMYK colour mode. Logos should be vector (AI, EPS, or SVG) or high-resolution PNG with transparent background. We can adapt most artwork formats. Just share what you have.

What if my check-in app is not listed on your platform grid?

Any app that can export a CSV or connect to a standard printer driver will work with our hardware. The printer grid on this site covers the 15 platforms we have tested and documented personally, but it is not exhaustive. If your platform can produce a badge template and send a print job to a networked or USB printer, we can support it. Send us your platform name and we will confirm before you book.
