vtprtoff is a simple program that turns off (or on) redirection of ASCII text to a printer connected to a terminal or terminal emulator. It uses terminal escape sequences to achieve this end.

Use the tty device file instead of stdout for output. This is defined as /dev/tty on this system. (This is operating system specific and may vary from system to system.)
Use the stdout stream for output, rather than a tty device file.
Forces vtprtoff to ignore the TERM environment variable and use the builtin control codes instead.
Undoes the effect of the -e option, which allows vtprtoff to attempt to find an entry in /etc/vtprintcap for the TERM value and use the corresponding control codes.
Print out a simple usage message.
Print out the license agreement.
Specifies an alternate file to use instead of /etc/vtprintcap.
Quiet mode. Suppress various status messages from being displayed.
Cancels the effect of the -q option, allowing normal progress reporting to occur.
Force the use of the TERM variable to perform a look up of the control sequences to be used in /etc/vtprintcap. If an entry in that file can't be found, vtprtoff will abort with an error.
Use the value of termtype instead of the value of the TERM environment variable when performing lookups in /etc/vtprintcap.
Display version information.
Specifies an alternate device file instead of /dev/tty to use.
Display important warranty waiver information. NO WARRANTY!
