Your post last week showed you trying to do something like: echo "\004" | lpr.
This doesn't do what you want.  To echo a CTRL-D, you need to precede the
CTRL-D with a CTRL-V (this tells csh that the next character is to be taken
literally).  Also, remember to use the -l parameter on the lpr call so your
print filter passes the control character through to the printer (actually,
you can just as easily do "echo ^D > /dev/ttya" and skip lpr/lpd altogether).
This should always "unzap" your printer.
