Slow Portrait Progress

I lost my good print of the reference photo that I'm using for this portrait of My friends Eddie & Vina Tanaka on Moloka'i, Hawai'i. I have it on digital file so I can use it as wallpaper on my desktop, but I can't run a good print of it because I'm out of inks. I have to figure out a way keep my desktop up longer before it goes to my screensaver pictures. Or something...
