Sometimes, the font is messed up on a printed version of a PDF file. It seems that this may be caused by the missing embedded fonts in the PDF file. The following shell function simplifies the process.

fixpdf.sh

# Ensure that fonts are embedded in a PDF file for correct printing
# Credit: http://stackoverflow.com/a/4234150
function fixpdf {
	# Print usage is no arguments are given
	if [ "$#" -eq 0 ]; then
		echo "Usage: fixpdf PDF_FILE [PDF_FILE ...]"
	fi
	# Check if ghostscript is installed
	if ! type gs >/dev/null 2>&1; then
		echo 'Error: ghostscript is either not installed or not in your PATH.'
		echo 'Run `brew install gs` to install ghostscript.'
		return 1
	fi
	# Iterate over given PDF files
	for file in "$@"; do 
		dir=$(dirname "$file")
		base=$(basename "$file" .pdf)
		gs \
			-sFONTPATH=/Library/Fonts:${HOME}/Library/Fonts \
			-o $dir/$base.fixed.pdf \
			-sDEVICE=pdfwrite \
			-dPDFSETTINGS=/prepress \
			"$file"
	done
}

Note that -sFONTPATH is currently set to values that are tailored for OS X. Adjust accordingly.
