We are living in a wonderful world where another day brings you another way of printing.

Scientists have found a way to print with sound. The new technology will help printers exert more precise control over the shape and viscosity of ink droplets.

Liquid droplets are used in many applications, from printing ink on paper to creating microcapsules for drug delivery. Inkjet printing is the most common technique used to pattern liquid droplets, but it’s only suitable for liquids that are roughly 10 times more viscous than water.

Thanks to gravity, any liquid can drip — from water coming out of a faucet to the century-long pitch drop experiment. With gravity alone, droplet size remains large and drop rate difficult to control.

Now, scientists have used sound to advance printing technology.

The researchers built a subwavelength acoustic resonator that can generate a highly confined acoustic field making in a pulling force 100+ times the normal gravitation forces (more than four times the gravity the surface of the sun) at the tip of the printer nozzle.

In the lab, scientists successfully printed microcapsules using a variety of liquid solutions, including honey, stem cell inks, optical resins and liquid metals.

You probably already know that printer ink is one of the most expensive liquids there is. Even with latest afford of the printer manufacturers to make ink more affordable to the people, you can find an exclusive French champagne to be cheaper in terms of dollars per ounce.

The bad news is, when you buy an ink cartridge or tank there is some amount of it that will never it the page. The good news is, there’s a way to mitigate this.

Canon is rolling out a new line of PIXMA printers: TS9521C, TS9520, TS9520, TS8220, TS6220, and TR4520. These models range from craft-focused printers to SOHO multifunctions with the price tag from $100 to $250.

PIXMA TS9521C is designed specifically for crafters and scrapbookers, not a regular Canon’s target audience. It supports pages up to 12 by 12 inches (most commonly used in scrapbooking), includes 45 built-in patterns for adorning the paper, and features a 4.3-inch touchscreen for navigating the menu.

HP Inc has posted an update to address a pair of serious security vulnerabilities in its InkJet printers.

The firmware update patches CVE-2018-5924 and CVE-2018-5925, two flaws that can be exploited by printing a file that triggers a stack or static buffer overflow, giving you the ability to then execute malicious code on the targeted printer.
