Typically this is a poorly written printer interface filter. I do two
things with all my text print scripts:
1. I strip all trailing blank lines which eliminates problems with
programs that pad everything out to 66 lines per page (many database
and accounting programs do this as well as nroff). The script does
this by counting blank lines, then sending that many newlines if it
comes to a non-blank.
2. End all HP print jobs with an ``ESC E'' sequence rather than a FF
(form feed). This resets the printer, printing anything that's in
the buffer, but doesn't print anything if the buffer's empty.

programmers they are mentally mutilated beyond hope of
