Does anyone make an ink-jet printer, to print erasable ink onto paper, so that the printing can be erased.?

The ';paper'; is irreplaceable original manuscript documents, and the erasable characters are; an unique reference and a barcode - which MUST be erasable so that the document isn't damaged. BTW the documents date from 1240 - 2006.Does anyone make an ink-jet printer, to print erasable ink onto paper, so that the printing can be erased.?
CAUTION


There is NOTHING I know of that is 100% erasable on 800-year old documents. (or any documents)





ANYTHING written on them in ANY form (pen, Pencil, ';Special Marker';) will cause a permant mark that CANNOT be erased completely.Does anyone make an ink-jet printer, to print erasable ink onto paper, so that the printing can be erased.?
I don't know if it is currently possible, but it is in development.

If I were you I would most certainly hesitate in attempting anything of the sort with any document that was even close to being 800 years old! if you want to reference them try keeping them in a box and placing the information on that. Much safer.
I've run into this before, I had to repair a printer where someone has taken bic erasable ink from ink pens and had used a syringe and put it in an empty cartridge. You can also purchase the ink from www.bicpens.com; the ink does work in a normal ink head but it needs to be thinned down. Becareful, it does get messy.
The only way is to retro fit a flat bed plotter with graphite tips.


You actually can purchase them new, however they will run you upwards of $10,000.
Write in pencil and then erase it!
