Frequently Asked Questions
I clicked print but nothing happened. Where do I start?
First, check that the Ultraprint Hub is running. Then verify the printer is online in your OS printer settings. Finally, check the Hub's printer list for any error indicators.
My prints are garbled or have wrong characters. Why?
This usually means the wrong printer driver is installed. Install the manufacturer's ESC/POS driver (not the generic text driver) and set the Hub printer type to 'ESC/POS Thermal'.
The printer was working yesterday but not today. What changed?
Common causes: the Hub was closed, the printer IP changed (DHCP), Windows updated and changed firewall rules, or the printer entered sleep mode.
Can I see a log of failed print jobs?
Yes. The Ultraprint Hub maintains a job log showing sent, failed, and queued jobs. Open the Hub and navigate to the Jobs section.
Should I restart Odoo or just the Hub?
Always restart the Hub first — it resolves 80% of issues. Only restart Odoo if the problem persists after Hub and printer restarts.
