Hello SimonHoSG,
It sounds like you've already tried some troubleshooting steps to fix the issue with your network printers. Since restarting the PC temporarily resolves the problem, it's possible that there is a software or driver issue with your PC that is causing the printers to go offline.
Here are a few more things you can try:
- Check for updated printer drivers: Go to the manufacturer's website for your printer (HP or Fuji Xerox) and see if there are any updated drivers available for your specific printer model. Download and install any available updates.
- Disable Windows Update Delivery Optimization: This feature can sometimes cause issues with network printers. To disable it, go to Settings > Update & Security > Windows Update > Advanced options > Delivery Optimization, and toggle the "Allow downloads from other PCs" option to off.
- Reset the network settings: Go to Settings > Network & Internet > Status > Network reset, and click the "Reset now" button. This will reset all network settings on your PC, so you'll need to reconnect to your Wi-Fi network and re-enter any passwords.
Hopefully one of these solutions will help resolve the issue with your network printers. Let me know if you have any other questions or concerns!
Best regards
Bblythe Xiao
