There are a few potential causes for printing problems. These troubleshooting steps are designed to isolate the cause of the problem so you know what to address.
Basic Setup
The first step is to confirm that the printer has been set up properly.
Troubleshooting
If you're unable to print after the initial setup, follow these steps to isolate the issue.
1. Is the printer working on its own?
If the printer was not set up properly, you won't even be able to make a "wired" print to it from your computer.
Testing
Plug your printer into a computer and print any file to your printer.
If You Have A Successful Print
Move on to step 2.
If You Have An Unsuccessful Print
Check for firmware updates through your printer manufacturer.
Delete and reinstall your printer driver and printer firmware
2. Is the WiFi network reliable?
If the WiFi network is incompatible or unreliable, the iPad (and therefore our app) won't be able to communicate with the printer.
Testing
Open the iPad's built in "Photos" app, select any image from your Camera Roll, and try a print.
If both devices are on the same network but you can't print from the Photos app, this suggests a problem with the WiFi network.
The issue might be a slow connection (which can happen on WiFi networks and hotspots), or the network may have a firewall or other security restrictions in place.
If You Have A Successful Print
Move on to step 3.
If You Have An Unsuccessful Print
First make sure you are still connected to the same network on both devices (step 2 under "basic setup" above).
Try disabling the WiFi Private Address setting, which can be found in your iPad settings within each specific network's settings.
Visit: Settings > WiFi > [Your WiFi Network / SSID]Connect to a second network if one is available, and try a new test print.
If a second network is unavailable or unreliable, you might be able to use one of these alternative network recommendations.
You may need to try a few networks before finding one that works reliably. Remember to "forget" any network you don't plan to use during the event.
3. Is the app printing?
Once the Photos app test print works, it is time to test your HALO app.
If You Have A Successful Print
As long as the Photos app test worked, Simple Booth should also be able to find your printer.
If You Have An Unsuccessful Print
When you print a picture through the HALO app, the print job is sent from HALO to Apple’s AirPrint protocol. From there, AirPrint handles the entire process of delivering the print job to the printer.
Check to see if the HALO app sent the print to Apple by pulling up your iPad's Print Center. See how to open your Print Center in this article under the section titled, "View or cancel your print job."
If you cannot see the new print job in the the Print Center, please contact our team.
If you see the print job in the Print Center, it may indicate a Wi-Fi connection issue or another problem beyond the app. While we’re here to provide guidance, please understand that we’re unable to troubleshoot printer connections once the print has left the HALO app and entered the Print Center. We appreciate your understanding and are happy to help however we can!
