I think Qimage has a schedule based test print mode if not mistaken, so when traveling it would print autopilot. I have heard very good things about the Pro-1000 and have used it, but not owned one. I have a Pro-10 that cannot handle ANY imperfect paper, so the vacuum on the canon is great. I have lots of sheet paper that from a bit of humidity change has slight curled edges, and this will cause a head strike.
I agree with Conner999's post, lol. A while back I had the Epson Pro4000, and that was the last Epson I promised to buy as I threw it out. I got the z3200 and had been really happy, yet leaving it unplugged, while it does better, it would also get clogged. Like the Canon, it is unavoidable to not run any small amount of print on a minimal weekly basis. So the printer does this on auto daily does a slight cleaning head.
I too would rather lose some ink for reliability. I almost purchased a lightly used Pro-1000 recently, but hardly had any inks in it. $700+ for the full set, while the printer is 1299 new with the inks(maybe larger inks), but still. I could not justify $500 for a "empty printer :-) but I still think that maybe it was OK.
