I happen to know a thing or two about printing, PDF, PostScript, PJL, Fonts and related stuff.
Also familiar with some bits and pieces of Linux, Unix, Samba and Solaris printing. Not to forget bash programming and Windows cmd.exe batch scripting. I also do consultancy in these topics.
If you want, I share some of this knowledge here and on Stackoverflow (SO). Just click to browse for all.
