Why Flinzy Works With More Printers Than Other Apps

1. What Do I Need?

Before you get started, make sure you have:

A supported printer (see section 2)
Your printer is turned on
Your iPad or Android tablet and your printer are on the same Wi-Fi network
For Wi-Fi printers: the printer is connected to Wi-Fi (check its screen or indicator light)
For USB printers (e.g. DNP) via Mac: your Mac is on, CUPS is configured, and "Share This Printer" is checked
For USB printers (e.g. DNP) via Windows: your PC is on, printer is shared, and Bonjour Print Services is installed and running

2. What Type of Printer Do I Have?

Not all photo printers connect the same way. There are two types — knowing which one you have determines your setup.

Wi-Fi Printers (e.g. Canon Selphy)

These printers connect directly to your Wi-Fi network, just like your phone does. No laptop or extra equipment needed — Flinzy finds them directly.

Tested and confirmed: Canon Selphy CP1500 Expected to work: All Canon Selphy models (CP1300, CP910, etc.)

Setup:

Turn on your printer and connect it to Wi-Fi using the printer's own menu
Make sure your iPad is on the same Wi-Fi network
That's it — skip to section 3

USB Printers (e.g. DNP DS620)

These printers use a USB cable and don't connect to Wi-Fi on their own. Your tablet can't talk to them directly — you need a Mac or Windows laptop/desktop on the same Wi-Fi network to act as a bridge.

Flinzy on iPad/Android → Wi-Fi → Your Mac or PC → USB cable → DNP Printer

Tested and confirmed: DNP DS620 via Mac Expected to work: Other DNP models (DS820, RX1HS) via the same setup

Setting Up on Mac ✅ Tested & confirmed

Connect your DNP to your Mac via USB and turn it on
On your Mac, open Safari and go to: http://localhost:631
Click Administration → Add Printer
Select your DNP from the list and choose the correct driver
Make sure "Share This Printer" is checked
Keep your Mac on and connected to the same Wi-Fi during your event

Once set up, skip to section 3.

Setting Up on Windows ⚠️ Untested — should work

Windows doesn't natively advertise shared printers in a way iPads and Android tablets can discover. You need one free extra program from Apple to fix this.

Step 1 — Install the DNP driver

Download and install the DNP DS620 driver from the DNP website
Connect your DNP via USB and turn it on

Step 2 — Share the printer

Go to Settings → Bluetooth & devices → Printers & scanners
Click your DNP → Printer properties → Sharing tab
Check "Share this printer" → OK

Step 3 — Install Bonjour Print Services for Windows (free)

Download Bonjour Print Services for Windows from Apple's website
Install it — it runs silently in the background and makes your printer visible to Flinzy

Step 4 — Keep your PC on during the event

⚠️ This Windows setup has not been tested yet. If your printer doesn't appear after these steps, use a Mac instead.

3. Connect Your Printer in Flinzy

Open your event in Flinzy and go to Event Settings
Scroll to Print Settings — you'll see the Printer section at the top
Tap Find Printer
Available printers on your network appear within a few seconds
Tap your printer to add it
Tap Print Test Page to confirm everything is working

If your printer doesn't appear, see Troubleshooting.

4. Choose Your Print Mode

Flinzy gives you two independent print settings — use one, the other, or both.

Auto-Print

Every photo prints automatically the moment it's taken. No guest interaction needed.

Best for: Events where every guest gets a print, no questions asked.

Requires a printer to be connected. You cannot start an event with Auto-Print on and no printer added.

Show Print Button

A print button appears on the guest photo screen. Guests tap it if they want a print.

Best for: Events where not every guest wants a print, or you want guests to control their own copies.

If no printer is connected, guests will see their device's built-in print screen instead — not ideal. Always connect a printer when using the print button.

Using Both at the Same Time

Both Auto-Print and Show Print Button can be on at the same time:

Every photo prints automatically
Guests can also tap the button for extra copies

Best for: High-volume events where everyone gets a print but some guests want more than one copy.

Which Mode Should I Use?

I want...	Use this
Every photo to print automatically, no guest interaction	Auto-Print only
Guests to choose whether they want a print	Print Button only
Every photo to print, plus guests can get extra copies	Both
No printing (digital only)	Both off

5. Set Limits

Max Guest Copies

(Appears when Print Button is on)

Caps how many copies a guest can request in one print session. Set it to 2 if you don't want guests printing 10 copies of the same photo. Default is 10.

Max Event Prints

A hard cap on the total number of prints for the entire event — auto and guest-requested combined. Once reached, no more prints go through and a message appears on screen.

Leave empty for no limit.

Example: Set to 200 if you've loaded 200 sheets and don't want your printer to run dry mid-event.

6. Using Multiple Printers

You can add more than one printer to an event. With 2 or more printers, you'll see an extra option:

All at once — every print job goes to all printers at the same time. Use this when you want multiple copies of the same photo (e.g. one for the guest, one for your display wall).

Take turns — print jobs alternate between printers. Use this to double your printing speed at busy events.

7. Troubleshooting

Printer not showing up in Find Printer

Make sure your iPad and printer are on the same Wi-Fi network — some routers split 2.4GHz and 5GHz into separate networks, keep everything on the same one
Turn your printer off and back on
For DNP via Mac: check that CUPS is running, the printer is added, and "Share This Printer" is checked
Move your iPad closer to the router

Printer was found before but not showing up now

The printer may have a new IP address. Remove it from your event and tap Find Printer again
Restart your printer

Test page prints but event photos don't

Printers are set per event — make sure the printer is added to this specific event
Check that Auto-Print or Print Button is turned on in settings

Photos are cut off or shifted on the print

Adjust the paper guide inside your printer tray
Make sure you're using the correct paper size in Fixed Print Settings

Prints are coming out very slowly (DNP via Mac)

Try restarting CUPS: open Terminal on your Mac and run: sudo launchctl stop org.cups.cupsd && sudo launchctl start org.cups.cupsd
Check for stuck jobs at http://localhost:631 → Jobs

The print button shows a system print dialog instead of printing silently

No printer is connected to this event. Add one via Find Printer and the button will print silently through Flinzy.

8. Why Flinzy Works With More Printers Than Other Apps

Most photobooth apps use AirPrint — Apple's built-in printing system. AirPrint only works with printers that have been officially certified by Apple. Most photo printers — including the DNP DS620 — have never been certified, which is why they don't show up in AirPrint-based apps like LumaBooth.

Flinzy uses IPP (Internet Printing Protocol) — a universal standard that doesn't require Apple's approval. Flinzy talks directly to your printer over Wi-Fi, without Apple as a middleman. This is why:

Wi-Fi printers like the Canon Selphy work with Flinzy without a laptop — no print server, no extra setup
USB printers like the DNP work with Flinzy via a Mac or PC, whereas AirPrint-based apps can't find them at all even with a Mac set up

In short: Flinzy supports more printers, with less setup.
