What were you trying to do?
Print a file at the printer, without a header page.
What's wrong:
lpr's -h acts as a toggle, which makes life really confusing
for users who have aliased 'ls' to 'ls -h', or who have set
the LPROPT variable to '-h'. This could be construed as
a bug.
What should have happened:
-h ought be -h, regardless of whether it has been used in
the optionlist already. A more sane syntax to turn off an
existing '-h' switch might be the use of '+h'.
Please describe any relevant documentation references:
echo "hi" > /tmp/foo
lpr /tmp/foo ; lpr -h /tmp/foo ; lpr -h -h /tmp/foo
lpr -h -h -h /tmp/foo ; lpr -h -h -h -h /tmp/foo
...these lines produce output which alternate between printing a
header page and not printing a header page. (Whether or not the
first invocation produces a header page depends on the value of the
LPROPT variable.)
