FROM NOW ON! DO NOT REGISTER YOUR PRINTER WITH THE MANUFACTURER!! High end Xerox copiers/printers are more or less "pre registered". You can't just walk into Wal*Mart and buy one, you have to deal with a Xerox rep. And you'll probably have some sort of service agreement. Cost per page is through the roof without one. With most high end equipment of this type it's just "that way". -- Hand crafted on October 20, 2005 at 05:50:20 -0400 Outside of a dog, a book is a man's best friend.

Better solution: used printer or copy machines from anonymous source like thrift shop, yard sales, etc where new buyer can't be tracked at all. Not eBay or online places since the seller would have buyer's address. You're probably not going to find a lot of this caliber used equipment for sale. Distributors go to great lengths to remove older equipment from the street. Especially if it's a competetor's equipment by the way. Even if you do, you're more likely than not going to have to deal with *someone* for your supplies. We're not talking "civilian" printers here, where you can order toner online or walk into Joe's Printer Emporium and buy anonymously. -- Hand crafted on October 20, 2005 at 06:03:19 -0400 Outside of a dog, a book is a man's best friend.

"Shaun Eli" wrote in message ups.com... Of course this is also a way to ensure that you eventually have to buy another yellow ink cartridge, even if all your printing is in black. Actually, I was thinking if you are doing something illegal with the printer, make sure it runs out of yellow ink first. -Dave |

"ER" wrote in message ... FROM NOW ON! DO NOT REGISTER YOUR PRINTER WITH THE MANUFACTURER!! ER How will that help when the serial number is on each page printed? Yeah, it might slow down the authorities tracking you, but when they find you, they'd still have proof that YOUR printer was involved. -Dave |

Ok, one million would be 50.000 twenty dollar bills, and if 'millions' means at leat two, then it would mean printing at least 100.000 twenty dollar bills. That would cost a fortune in yellow ink!

All printers have charisteristic quirks which can be used in court
cases. Its similar to the days when metal fonts on each typewriter was slightly different in shape and angle. Xerox's identifiers justs makes it easier. |

The serial number and the date.

SSW wrote: EFF reveals codes in Xerox printers NEW YORK (AP) -- Just because a document from a color laser printer doesn't carry your name doesn't mean no one can trace it back to you, privacy advocates warn. The Electronic Frontier Foundation says it has cracked the tracking codes embedded in Xerox Corp.'s DocuColor color laser printers. Such codes are just one way that manufacturers employ technology to help governments fight currency counterfeiting. "Underground democracy movements ... will always need the anonymity of simple paper documents, but this technology makes it easier for governments to find dissenters," said Lee Tien, EFF senior staff attorney. "Even worse, it shows how the government and private industry make backroom deals to weaken our privacy by compromising everyday equipment like printers." Researchers found patterns of yellow dots arranged in 15 by 8 grids and printed repeatedly over every color page, said Seth Schoen, a staff technologist at the San Francisco-based civil-liberties group. The dots are visible only with a magnifying glass or under blue light, which causes the yellow dots to appear black. By analyzing test pages printed out by supporters worldwide and by staffers at various FedEx Kinko's locations, researchers found that some of the dots correspond to the printers' serial numbers. Other dots refer to the date and time of the printing. Xerox spokesman Bill McKee would not provide details about the technology. He said the company "does not routinely share any information about its customers," though it does respond to requests from law enforcement... The EFF is now studying other printers from well-known manufacturers with similar tracking codes... Adobe Systems Inc. has acknowledged quietly adding the government software to its Photoshop software at the request of regulators and international bankers. But David Skidmore, a spokesman at the Federal Reserve Board, said that the technology, known as the Counterfeit Deterrence System, was aimed mostly at personal computers and ink-jet printers - not the high-end machines like DocuColor. --------------------------------------------------------------------------------- See pic at http://www.engadget.com/entry/1234000663063763/ |
