The first thing that you should know about creating a PDF file is that a PDF file is actually gets printed. In other words, in case of PDF files, creation means printing. A number of people are unaware of this tiny fact –so I thought on mentioning it at the onset.
To create PDF files, basically you need to install a PDF printer in your computer. The output of this printer would not come on paper but in the form of a PDF file.
There are innumerable PDF printers available out there. The one that I use, and I am quite satisfied with it, is CutePDF Writer. It is free both for commercial and non-commercial use. CutePDF Writer supports Microsoft Windows 98/ME/2000/XP/2003/Vista/7 (both x86/x64). One of the drawbacks is that you would need to separately install a PS2PDF (post-script to PDF) converter. Ghostscript is one such converter available freely.
You can download CutePDF Writer from here
And download Ghostscript converter from here.
Once you have downloaded both the software, run the CutePDF Writer setup. After the installation is complete you can convert anything into a PDF. To do so, open the file you want to converter into PDF (e.g. an MS Word document) and then go to print option (usually available as File > Print). In the Print dialogue box –select “CutePDF Writer” from the printers list (refer to the image below). You can select the pages you want to print to PDF.
