You can create a PDF file from virtually all software that can print. This results in the conversion of other formats to PDF (Portable Document Format)
1) Have your file you're going to convert opened in the proper software.
2) File->Print, and choose PDF Creator printer from the printer list.
3) Click the "Properties..." button on the right side of the printer list, and you can change the PDF options as you would have them appear in the PDF format. This includes the paper size, image compression, encryption, color space, etc. Change the settings to your preferences on the Print dialog box. Confirm the print job by clicking OK.
4) A creation dialog (Save-As dialog) will appear. You'll be given options about general document information for your PDF. Select and set these accordingly. Then save the file and specify the folder location in which you want it saved. You have to save it to create the PDF. The file will save with a .pdf file extension.
5) Once saved, if you didn't check the option to automatically have the PDF launched after creation, you may have to open the PDF again using a PDF viewer.
