Inkless printer Answered

What if you put a laser cutter on low power and used it like a printer? What if you made an insert for inkjets to accept a low power laser? No more ink - ever! just paper or anything else you wanted.

Haven't we discussed this elsewhere? Laser printers do not shine a laser onto paper - they use it to charge a roller that picks up toner in exactly the same way as a photocopier. If you want to burn the image directly into the paper, you're going to need a flat-bed plotter, with a laser in place of the pen, plus careful control of the burn - singing without evaporation.

You could cover it in lemon juice, then use the heat of the laser to darken the parts you want. (text)

There's an idea ! Replace the ink in inkjet cartridges with lemon juice and make the message a high tech secret one. Just make sure you have all the "pulp" out of the juice or it will clog the jets LOL

Actually, bubble jet printers use heat to spray the ink.  I wonder if you used the lemon juice in a bubble jet cartridge would this heat be enough to color the juice and make it visible.  You could only do black and white but it would be cheap.

Hmmm, I suppose it would depend on the amount of heat applied.....it would break down fairly quickly though, I would assume.

Don't know.  Maybe I will try to get an old bubble jet from a thrift store or something and try it.  Hope it doesn't explode in flames : )

I will probably used the store bought stuff.  I will have to test it to see if it still discolors when it is heated.

LOL The only problem is that you couldn't leave the note out in the heat.

I think that this cannot be done, the laser's do not print directly on paper. It uses a drum which contains powdery substance that get prints on the paper. you can get more information here:

I posted something about paper & laser engraving a few days ago.
The main problem is that paper reflects about 95% of most wavelengths laserlight.
It has been done before though; Atl east with a industry grade laser engraver

Also there is a laser wood burner instructable where I have asked this, see
https://www.instructables.com/id/Laser-wood-burning-pen/

The lemonjuice idea came to my mind too ;-)
In general, a small heat source would probalby do the trick to plot on paper either by slightly burning it or burning the carbon in lemon juice or another substance.

He doesn't want to hook a toner drum out of a laser printer into an inkjet printer, as that's just pure madness, but rather use an actual laser out of a laser cutter, pretty easy to understand. Now I think that it's a good idea, but I think it if could be done it would have been done already.

Do you know how a laser printer works?
What if you put a laser printer on low power and used it like a printer? That doesn't really make sense. What do you use your laser printer for, other than as a printer?
