Epson 3880 - Leave it On or Turn it Off

Probably may print to it every 2 weeks or so. Maybe less....

Is it better to leave the Epson 3880 always on or off ?

Aside from clogging - non usage, is it just a matter of the 1st 2 or 3 prints being off and the rest should be just fine, if I went with the leave it off routine
