Recently, many users have reported the problem that the XP system cannot connect to the win10 system to share the printer. Today, the editor has sorted out the method of adding a win10 printer under XP. It can also help friends who cannot connect to the Win10 printer. It has been tested by countless netizens.
1. Open Printers and Faxes, then "Add Printer" 
2. Select the local printer connected to the computer;
3. Continue to the next step
4. Use a useless port, usually the first one is useless win10 www.xitonghe.com/win10/ , continue to the next step
5. Install the printer driver. After installation, it is best to replace the existing driver, otherwise it will prompt that nothing can be found. I forgot, anyway, I can add it successfully by replacing the driver.
6. Right-click to open the printer properties after adding, and then do not close the window
8. Re-add the printer, click on the network printer or the printer linked to other computers (ie shared printer)
9. Click the name of the printer in the printer window above the shared printer you want to connect, and copy it
10. Return to the window that has not been closed just now and add the port. New port type, then paste the printer name you just copied from the shared printer
(step 10 should be: Add Port >>>> Check Local Port >>>> New Port. New Port Name: Printer name copied in step 9 . Then, configure the printer's port to the newly created port)
11. Then wait for a while and it's OK, don't go to the point, just wait, otherwise it is easy to have no response and shut down. Generally, XP will be a bit slow.
OK
