[Gambas-user] How to sent a line line to a lp1 printer and form to lp0 printer directly.

[Demosthenes Koptsis]

in shell you can do it by

echo "Program started" >> /var/log/messages

note* >> means redirection to the end of file, so it is append

if you type > you will erase the contents of the file and put only
"Program started"

now you can use this command with SHELL.
