My printer says my ink cartridge is empty. I think it's lying.

My printer says my ink cartridge is empty. I think it's lying

Solution:    

   
      You may be right. Printer out-of-ink messages are notoriously unreliable. The good news: You can try various hacks to get around those ink cartridge controls. We're not suggesting that all, or even some, of these reader tips will work with your printer, but they're worth a try. One tip reveals how to reset ink cartridges for various HP printers. And a video on this page shows how to revive an "out of ink" Epson cartridge. If you're feeling adventurous, check them out.

My prints are too light, too spotty, or have horizontal lines.

My prints are too light, too spotty, or have horizontal lines.

Solution: 
 
   You may have a clogged print head, a problem that can occur if you use an inkjet printer infrequently. Your printer's utility program can clean out the dried ink, and print a test page for inspection. The step-by-step instructions on how to do this vary by printer. From the Windows 7 Start menu, click Devices and Printers or Control Panel, and look for your printer's utility app. For additional details, read "Solve Inkjet Printer Problems." For more tips on unclogging ink nozzles, go here. (Again, these steps may vary slightly for Vista and XP users.)

Windows is sending print jobs to the wrong printer

Windows is sending print jobs to the wrong printer

Solution: 
 
     For some mysterious reason, 
Windows may select a new default printer--the one it automatically sends print jobs to. (This happened to me when I upgraded from Vista to Windows 7.) To fix this glitch in Windows 7, click Start (the Windows icon in the lower-left corner of the screen) and select Devices and Printers. Under Printers and Faxes, right-click the printer you want to make the default, and select Set as default printer.

    If you're using earlier versions of Windows, these steps vary a bit. Here are instructions for Windows XP and Vista users.

Ink and/or toner costs too much

 

 Ink and/or toner costs too much.

Solution: 
    
    PC World has written a lot about the printing industry's sneaky practices over the years. To wit: They snare you with dirt-cheap printers sold at or below cost, and then stick it to you later with ultra-pricey consumables.

   Based on our tests, we can't recommend third party vendors' remanufactured or refilled ink cartridges, which may not give you your money's worth. One cost-saving solution is to buy higher-capacity's Compatible of toner cartridges. If you print a lot, try an ink cartridge with a 250-plus page yield, or a toner cartridge with a 2,000-plus page yield.

Printing is too slow.

Printing is too slow

Solution: 
   
    Rev up printer performance--and save ink in the process--by reducing print quality for everyday output. While printer settings vary by model, here's how to switch to draft-printing mode in most Windows apps. Select Print and Properties, and then look for a setting that reduces print quality. With the HP Photosmart 8450, for instance, change the default print quality setting from Normal to Fast Draft (click screen-shot at right). Other speedup suggestions: Print pages from websites without graphics, and add RAM to your printer, if possible. Read "Speed Up Everything" for more tips.

U.S. Artist Gary Staab Uses 3-D Printing to Replicate 5K-Year-Old Mummy

U.S. Artist Gary Staab Uses 3-D Printing to Replicate 5K-Year-Old Mummy

    MAINZ, Germany — Some 5,000 years after his violent death, one of the world's best-known mummified bodies has been replicated by an American artist using 3-D printing technology.
  
   "Ötzi the Iceman" became a media sensation in 1991 after he was discovered by a pair of German hikers high in the Italian mountains.Named after the Ötztal Alps in which he was discovered, Ötzi likely bled to death after he was shot in the shoulder with an arrow more than five millennia ago.

     Most of us can only view the body in darkened room at Italy’s South Tyrol Museum of Archaeology — a necessary measure to protect Ötzi's uniquely preserved body.But thanks to the efforts of Missouri-based artist Gary Staab, who specializes in making replicas of archaeological finds, three models of the Iceman have now been created and will be used for scientific lectures in the U.S."It was probably the most difficult project I ever worked on," the 48-year old told NBC News.

   

     Staab spent more than 2,000 hours on the project and has previously sculptured replicas of mummies from Peru and Egypt, as well as the ash figures from Pompeii.After examining the original Ötzi in Bolzano, Italy, last summer, he used CT scans to create a medical-grade 3D-printed model using liquid resin.The stereolithography was done in a giant 3-D printer at Belgium-based company Materialise. However, the scans were not able to capture all of the body parts, such as the hands and ribs, so the model was completed with paint and clay.

   "Staab succeeded in carving out fine detail," said Angelika Fleckinger, director of the South Tyrol Museum of Archaeology. "The result of his work is therefore confusingly similar to the original."One of the models will be included in a traveling exhibition due to start in October 2017 at the North Carolina Museum of Natural Science, in Raleigh. The other two will be used for teaching purposes in New York's Cold Spring Harbor DNA Learning Center.

    Staab said he hopes "to please the scientists" with his creations

The first 3D print satellite was successfully launched

The first 3D print satellite was successfully launched

     Previously, Boeing using 3D printing technology to create aircraft parts caused many conservative concerns, reflecting the rise in recent years, 3D printing technology has not been widely recognized by the public. And recently, a Russian initiative for 3D printing technology provides a strong endorsement.

   

   Recently, the Russian astronaut Sergei Rajazansky (SergeiRyazansky) in the International Space Station successfully launched a mini satellite, and this satellite is almost entirely by the 3D printing technology.The TomskTPU-120 is Russia's first 3D print satellite, developed by Tomsk Polytechnic University and Southwest State University. After the launch is successful, the satellite is expected to run in its orbit for 6 months, in addition to measuring the Earth's surface and transmission data, the satellite will also be broadcast through the radio station in 11 languages to commemorate the first man-made earth The 60th anniversary of the launch of satellites and the 160th anniversary of the birth of the space.

    3D printing technology for the manufacturing industry has brought great changes, and with the reliability of this emerging technology, stability has gradually proved that it is expected for human production and manufacturing to bring more huge changes.
