They are in LaTeX format, so it is hard to read the ascii version unless you know LaTeX very well. If you know how to run LaTeX, then just download the notes*.tex files, latex it, and then run dvips to get a postscript version of the notes you can print. Otherwise, just download the postscript version which is ready for printing on any postscript printer, including the ACS printers in the basement of ECS.
Note that you can also access the class notes directly using ftp from ftp.umbc.edu in directory /pub/users/strow/Physics_303. The names of the files there should be self explanatory.
