The pico projectors I've seen are low res, less than NTSC TV.
And 1080i isn't even as high a resolution as my 19" monitor.
It has been said before here that for a laser printer or inkjet to be high enough res for making fine pitch PCBs, they must be at least 600dpi.
Take 1280x1024 and shrink it down to 600dpi, that's about 2x1.6 inches. Not very big.
