I can print again after my printer got repaired this morning. Apparently, my story was so unbelievable to the Epson technician I was talking to on the phone that he was constantly trying to convince me that my eyes were lying to me. Apparently, if the platen is out of alignment, you can have all sorts of unbelievable problems. Regardless, the technician from Decision One was able to diagnose a truly obscure problem and fix it in short order, while we reminisced about the evolution of digital printing. Now it prints immaculately without ruining every piece of paper I put into it. All in all, it was a fairly pleasant experience and now I can experiment and try to make 24"x24" images when I get the proper roll paper. I think I may need to make my way to WestPhoto in the next few days to snag some big rolls of paper after I make the proper printing targets to evaluate which paper will reproduce the colors in a satisfactory way.
