[System] adds/deletes virtual printers and virtual printers in windows.

[System] adds/deletes virtual printers and virtual printers in windows.

Because the project needs to add multiple virtual printers to the windwos system (which can print the paper normally), find out the system function.

Run rundll32 printui. dll and PrintUIEntry in CMD and get the following prompt in the pop-up box.

To add a printer, first check whether the local port exists on the printer page of the control panel. The virtual port that can be printed normally is (NUL :). If it does not exist, you need to manually create it.
