It sounds like you're encountering issues with printing from your HP 1220C printer connected via a WPS54GU2 print server on a Windows 7 x64 system. The fact that you can ping the print server and print a test page from the print server itself indicates that the connectivity between the devices is established. Here are some troubleshooting steps you can follow to resolve the issue of Windows not detecting the printer: 1. Add Printer Manually: - Go to Control Panel > Devices and Printers. - Click on "Add a printer" and choose to add a local printer. - Select the port that corresponds to the IP address of your print server (e.g., Standard TCP/IP Port). - Follow the on-screen prompts to install the printer driver. 2. Check Printer Sharing: - Ensure that printer sharing is enabled on the print server and that the printer is shared with the appropriate permissions. 3. Driver Compatibility: - Confirm that the driver you have installed on Windows 7 x64 is compatible with that operating system. Sometimes older drivers may not work as expected. 4. Firewall and Antivirus: - Temporarily disable the firewall and antivirus software to check if they are blocking the printer connection. 5. Restart Print Spooler: - Sometimes restarting the Print Spooler service can help in resolving printing issues. You can do this by: - Press Win + R, type services.msc, and press Enter. - Locate the "Print Spooler" service, right-click on it, and choose Restart. 6. Check Printer Status: - Ensure that the printer is turned on and properly connected to the print server. 7. Update Printer Driver: - Try updating the printer driver on the Windows 7 x64 system to ensure compatibility and functionality. 8. Network Settings: - Verify that the network settings on the Windows 7 x64 system are correct, especially the IP configuration. By following these steps, you should be able to troubleshoot and potentially resolve the issue of Windows not detecting the printer connected via the WPS54GU2 print server.
