A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

HTML5 and CSS3 Fundamentals

Build a website from the ground up by first learning the fundamentals of HTML5 and CSS3, the two popular programming languages used to present content online. HTML deals with fonts, colors, graphics, and hyperlinks, while CSS describes how HTML elements are to be displayed.

So I guess laser printing bar codes onto fruit/vegetable skin has been a thing for a while now. Slipped my radar. I only heard about it recently from this article where a market in the UK is using the technology on Avocados.

The labels, which are etched onto fruit's skin with lasers instead of stickers, will save 10 tonnes of paper and five tonnes of glue every year according to M&S.

Here is the company behind the technology:

Berries, grapes, etc are going to be in a package anyway. This is for fruit that gets those little individual stickers: avocados, grapefruit, oranges... good question though about thin skin like apples, may not work so well.

In another year, they'll probably be dispensed like gum-balls.
