For Printer version 126.96.36.199 and lower to work properly, all you need is .NET Framework 3.5, and from version 188.8.131.52 onwards, you will need .NET Framework 4.6.
If you are using the latest Windows 10 operating system, you have already installed .NET Framework 4.6. In such cases you can simply download and install Printer.
Other Windows versions
Windows Vista and Windows Server 2008 include .NET Framework 3.0, and on Windows 7 and in Windows Server 2008 R2 by default is installed .NET Framework 3.5. On the other hand, Windows 8 has .NET Framework 4.5. If the installer does not detect the required version of .NET Framework in your system, Printer will ask you to download and install it during the installation.
