No, reading and writing to the same file usually doesn't work (unless
you have a very good reason to do it). But using printf seems weird. It
just forces the shell to hold the whole output of sed in memory to be
able to pass it to printf.
Isn't a more conventional way to do that
sed -e '...' "$1" >"$1".new
mv "$1".new "$1"
?
