If you would like to avoid having to worry about inadvertently installing adware with such a tool, though, Stefan Heinz offers a free program, FreePDF, which I've used on a Microsoft Windows 8 system, that provides a printer driver that will allow you to print from any application run under Microsoft Windows to a PDF file. Unlike much of the other free PDF printer driver software, you don't need to worry about adware being installed with the software. The developer states at What is FreePDF:
Freepdf.exe really is free - no hidden costs and no advertising. No spyware, no automatic updates. Simply because I also do not like this in other "freeware".
The developer also notes "Freepdf.exe is , strictly speaking, a graphical user interface for Ghostscript." Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. So you will need to install Ghostscript before installing FreePDF.
To use FreePDF, take the following steps:
For the 64-bit of Ghostscript 9.19 for Windows, the default installation
C:\Program Files\gs\gs9.19\, but you can select
a different directory during installation.
That's all there is to installing the software. The software installs files
C:\Program Files (x86)\FreePDF_XP, including its manual, which
is available as a PDF file in German and English.
I had a lot of applications open when I installed Ghostscript and FreePDF and needed to reboot the system after installing them. I didn't see a notification indicating the system needed to be rebooted, but nothing printed to a PDF file until after I did so. When I rebooted and logged in again, I then saw the FreePDF print options window.
To create a PDF file using the software, print from an application, but instead of printing to the printer you might normally print to, select "FreePDF" as the printer.
You will then see an options window where you can choose the "PDF Profile", which can be set to "eBook", "High Quality", or "Medium Quality". You can select a file name for the output PDF file and the location of where you wish to save it with "Save As".
If you wish to check the VirusTotal scan of the file used to install the software, the current report for a recent antivirus scan of the software is available at the VirusTotal site or as a 1.5 MB PDF file here. Of course, you can always upload a file you've downloaded to the site to get a more current scan. Information for the 4.14 version of the installation program is shown below:
