The tool recreates the "LTMEAT" print method by flooding a page with thousands of iframes—often up to 2,500 at once.
When the user attempts to print a page containing this massive volume of iframes, Chrome attempts to render them all for the print preview.
The tool is frequently discussed in communities like 3kh0's ext-remover which focus on gathering ChromeOS exploits into a centralized archive for research and educational purposes. Common Misconception: 3D Printing "Blobs" ext printer blobby boi
It was developed by Blobby Boi and is hosted as an open-source project on platforms like GitHub.
(often searched as "ext printer") is a specialized software exploit created by the developer Blobby Boi designed to target ChromeOS environments. Serving as the successor to the older "ExtHang3r" tool, it allows users to intentionally "freeze" or "kill" browser extensions, which is commonly used to bypass administrative filters or monitoring software on school-issued Chromebooks. How ExtPrint3r Works The tool recreates the "LTMEAT" print method by
For reasons tied to browser architecture, printing a page with excessive iframes "hangs" or freezes the embedded extension pages rather than the host page.
Unlike previous extension-freezing methods, ExtPrint3r is noted for being more stable and lasting for longer periods. Common Misconception: 3D Printing "Blobs" It was developed
The core mechanism of the exploit leverages a vulnerability in how Chrome handles large amounts of embedded content during a print command.
This exploit specifically targets extension pages listed under web_accessible_resources , making it a consistent method for disabling specific background processes without crashing the entire operating system. Key Features and Context
Due to the keywords "printer" and "blob," this term is sometimes confused with . In 3D printing, a "blob" or "blob of death" is a physical failure where filament leaks from the nozzle and engulfs the hot end. While both involve the word "blob," they are entirely unrelated: one is a digital exploit for ChromeOS, while the other is a hardware malfunction in additive manufacturing.
