Printing Not Working? Try These Fixes

If your labels aren't printing correctly, try these solutions in order:

1. Check Connection

• Is the printer powered on and ready?
• Is the USB/network cable securely connected?
• Can you see the printer in LabelInn's printer list?

2. Restart Everything

1. Close LabelInn application
2. Turn off the printer
3. Wait 10 seconds
4. Turn on the printer
5. Open LabelInn again

3. Check Label Media

• Is there label media loaded?
• Is the media sensor aligned correctly?
• Try running a printer calibration (see printer manual)

4. Test Print from Printer

Print a test page directly from the printer (usually by holding the Feed button). If this doesn't work, the issue is with the printer hardware.

5. Check Print Settings

• Verify label size matches your media
• Check print speed and darkness settings
• Try reducing print speed if labels are unclear

Still Having Issues?

If none of these solutions work:

1. Go to Settings → Support → Collect Logs
2. Send the log file to support@labelinn.com
3. Include your printer model and describe the issue
