Screen and printed plots

By default, plt makes an X11 screen plot. To make a printed plot, use the option -T lw, and pipe the output of plt to lwcat(1). Under Unix, GNU/Linux, or MacOS/X, lwcat uses the standard lpr print spooler to send plt's output in PostScript format to the default printer. When running with a Cygwin/bash window under MS-Windows, or when using lwcat's -gv option under Unix or Linux, the PostScript output is displayed on-screen using GhostScript (GSView under MS-Windows, or gv otherwise; these programs can save the output in a file or send it to a printer).
