Surely more than once you have heard about virtual printers, but it has never been clear at all what they mean. Well, it is a printer that is added to your computer, although physically it does not exist. When you print a document (or any other printable item), instead of printing on paper, what it does is generate a file with what has been sent to print. And this is exactly what this ActMask SPL Virtual Printer SDK does.
Because the virtual printer that ActMask SPL creates Virtual Printer SDK is responsible for creating in EMF or SPL format any kind of printable item that you have indicated.
The EMF extension is the format where emails are stored in many mail programs, and the SPL extension is the print queue that is generated in Windows every time you send print.
You can free download ActMask SPL Virtual Printer SDK 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
