打印机共享了连不上

There could be a number of reasons why your printer is not connecting to your shared printer. Check the cables and make sure they are properly connected. Ensure the printer is properly powered on, and make sure the printer is set up correctly in the printer settings on both the host computer and the computer you are connecting to it. Additionally, make sure the printer is supported by the software and operating system you are using. If you are still having trouble, try restarting your computer and the printer, and then try reconnecting. If all else fails, contact the manufacturer for assistance.
