<Just make sure it's Teflon, or Tyvek based paper (if such things <exist), using some very high-tech ink/toner most modern papers (that <I know of) have a finite shelf-life. Now papryrus-- that's rugged! <S.L. = Several millenia Not a big thing, use a low acid archival paper intended for that use. Also the printing should be done using an impact technology, it puts the ink deeper into the fibers. Ink jet would be good save for the ink stability is unknown, I'd suspect it's good though. Toners are wax resin based and while storage life is good it's not great. Allison
