  If your Deli All in One Printer isn't working after you send print jobs, here's what to check: 1. Make sure the printer is turned on and in a normal operating state. Try restarting both the printer and your computer. 2. Verify the printer is correctly connected to your computer. 3. Ensure that you've selected the correct printer. Check the Printer Helper for print jobs. If it shows the printer is offline or the wrong printer is selected, re-add the printer. Remember, if the printer was added via USB, it needs to be physically connected via USB.

  If your Deli All in One Printer cannot be added via the USB cable after successfully installing the driver, try these steps: 1. Check the USB cable for any visible damage. If damaged, replace it with a new one. 2. Go to your computer's printer settings and plug and unplug the USB cable. See if the printer appears (or any unknown device appears). If nothing appears, the USB cable may be faulty; replace it. 3. If the printer is recognized as an unknown device, use the Printer Helper to manually add the printer via USB. If this fails, reinstall the driver.
