Laser printers sure have come down in price, making the technology available to just about anybody for personal use.
But laser printers have some “features” that probably are not explained about in the users manual. In fact, not even mentioned at all and few people are aware of their existence.
Whenever you print something on a page, that laser printer also takes it upon itself to put a message on the sheet of paper.
A secret message that consists of yellow dots so small that they are invisible without magnification and special blue lighting.
Here’s an example…
Now let’s look at the same piece of paper but with magnification of 60 times. Can you see the faint yellow dots on the paper? They would be really easy to overlook.
It would be really easy to still think that it was just some flaw of the paper that you used or perhaps the occasional fiber out of place. So let’s look at the printed paper again but with a special blue light with slight magnification.
Now for clarity, let’s put a big yellow dot where any of those tiny dots are shown by the blue light illumination.
Remember, the area of yellow dots are so small and blended in to the white background so well that they are completely invisible. You would need the technical know how to even begin to look for them, much less find them.
So what is it? Well, it’s a coded message and all printer manufacturers have been putting these coded messages on their printer paper for quite a while at the request of the government.
They were discovered and publicized by the Electronic Frontier Foundation. A organization that I highly recommend readers learn about and support.
In this new world of technology and computer information, they’re the group needed with the necessary technical knowledge to oversee and fight the abuses.
