yeah, i was thinking the same and coming here to find answers/solutions, but i could only see question like you hv posted...
anyway, i'm thinking of changing the sensor resolution to a lower value one, eg. let's say original is 180dpi, reducing to by 5 fold becoming 36dpi. It'll cheap the printer to printer 5 times wider, almost 5 feet! Of course, the picture u send to print has to be distorted in a way that it'll print in a right proportion (eg. original pic WIDTH shrunk by 5 times). Then, the picture width resolution will also be sacrificed by 5 times, example original resolution is 5760dpi x 1440dpi, then after "cheating" it, it'll b reduced to 1152dpi x 1440dpi....
how does this hypothesis sound? anyone any voice??
thanks,
Andy
