Digital BW, The Print

I'm looking for help from any mac osx users. I just installed a cis system on my 
2200 and want to keep it clear of troubles. I know that letting it sit idle is asking 
for trouble. I was thinking of using the startup feature to automatically start the 
computer every day, then have a script in the startup items that will print an 
image to keep the heads working at least once per day. I don't know anything 
about scripts, or if I even need to do it this way. Any ideas to accomplish my 
mission?
