Start with the simple connection checks
- Make sure the printer is powered on and is not showing a paper, ink, toner, or door-open warning.
- Restart the printer and the computer. If the printer uses Wi-Fi, confirm it still shows your current network name.
- Try printing from another device. If every device fails, the problem is probably the printer or network rather than one computer.
Clear the queue and choose the right printer
- Open the printer queue and cancel jobs that are paused or stuck. A single damaged job can hold everything behind it.
- Confirm the selected printer is the physical printer you intend to use, not a PDF printer or an old duplicate.
- In Windows, turn off "Use Printer Offline" if it is enabled. On a Mac, remove and re-add the printer only after the basic checks fail.
Check Wi-Fi and printer software
- If the router or Wi-Fi name recently changed, reconnect the printer using its screen or manufacturer app.
- Restart the modem and router only if other devices also have connection trouble.
- Install the current driver or printer app from the manufacturer. Avoid random driver-download websites.
Stop guessing when the problem keeps coming back
Ask for help if the printer repeatedly disappears, will not reconnect to Wi-Fi, or still shows offline after the queue and driver are refreshed.
