Along with what Phil says, you can also set the printer to check the nozzles before each print. This takes a minuscule amount of ink (minuscule is overstating it, it's ridiculously small amount).
This would give you fail safe printing while the printer is not attended, worse case scenario you have one ruined print and the printer stops and waits for you because it couldn't clear the clog. Most likely in 3 attempts it would clear the clog and keep printing.
Don't underestimate the need to control humidity, it is a major factor with clogged nozzles on epsons and failed heads on Canon's and HP printers. I just installed a self filling humidifier that can output 8 gallons a day, water is supplied through an RO system. I keep the room at 45% and my clogs have dropped dramatically. Additionally my paper's are less curly, a nice side benefit.
