This post explains how to embed fonts in PDF file.
Embedding the font in the PDF file is useful when you are preparing a paper for conference submission or you want to ensure that your PDF file looks exactly same on other's machine as it does on your computer.
In this post I will explain how to do it on Linux machine. I am not sure how to achieve the same on Windows computer.
We will use tool "pdffonts" to examine PDF file.
$ pdffonts mypaper.pdf

The important columns are name and emb. The "name" column displays the name of the font and the "emb" column shows whether that font is embedded in your PDF file or not. "yes" is "emb" column indicates that the font is embedded in the PDF file and "no" indicates that the font is not embedded in the PDF file.
For example, in the above oputput, Arial, and Arial,Italic fonts are not embedded in the PDF file.
To embed the un-embedded fonts into your PDF file using PDFLaTex:
$ updmap --edit
The above command will open the configuration file for pdflatex.
pdftexDownloadBase14directive and make sure it is true. That is, when you're done, the following line should be in the file:
Save the file and rebuild your PDF file using "pdflatex".
Then check your PDF file using "pdffonts" command. It should now have embedded all the fonts use in your PDF file.
If there are still some fonts missing then it might be because your have embedded another pdf file (as a graphics) into your "mypaper.pdf" file.
In that case, you need to embedded the fonts into those embedded PDF files as well.
If you included figures in your PDF file then follow the steps given below:
1. Convert your PDF file to PS file
$ pdftops mypaper.pdf
2. Convert back ps file to pdf using "prepress" settings
$ ps2pdf14 -dPDFSETTINGS=/prepress mypaper.ps
Conversion from PDF to PS and again back from PS to PDF my cause some formatting errors. I recommend you to double check your PDF file for formatting errors.
3. Check PDF fonts using pdffonts command
$ pdffonts mypaper.pdf
