Both the Roland and Epson printers will stop when an ink is OUT. Simply change the cartridge and printing will resume, usually with no ill effects. Even my Epson 2200 (13 x 19 format) at home will stop, allow me to change the empty and will resume printing the file. On the Roland, go to the Menu on the front of the printer and scroll to Ink Control and set it to Stop, not Continue. You may have not had that parameter set correctly, though I think the default is to Stop. The Epsons will stop automatically. Don't change any ink when it says it is Low. That is just a heads-up to let you know it will be running out of that color in the near future. Keep an extra of each color and you'll never have to worry about ruining a print. I have a friend who let his printer beep for 18 hours til he got the color he needed, plugged it in and was good to go.
