Need sideways/landscape print

[Roger Knopf 5502]

I am in search of a program to do sideways printing on a dot matrix
printer (HP Thinkjet). What I mean is, a program which will take an
ascii input stream and print it sideways so you can get 132 columns
on an 80 column wide printer. This program must run under Unix.
C source preferred.
