Having a printer is great, but the costs for the ink cartridges can get out of control, especially for businesses that a large number of printers to purchase ink for. Having your office at home can be costly as well, as you will most likely be using your printer on a daily basis, not to mention the kids using it for their homework. Many homes today have multiple computers, which means multiple printers. Of course, the easiest way to go would be paper-free but unfortunately that lapua 308 brass doesn't always work. By following a few simple guidelines, you can extend the life of your black ink cartridge.

The use of draft printing will extend

The life the cartridge immensely, as this option allows you to print with minimal ink. This also speeds up the printing, as well, so you get the paper in half the time as you would have, printing it in the best quality mode. Save the best or top quality for your final print.

You can choose this option from the file tab and choosing the print option. This will open the box for printing and print choices. You will want to choose the paper/quality tab and select the setting for printing such as the draft quality. Your file will print at a lower resolution allowing you to save on the ink.

If you're dealing with a long document, print two sheets to a page if you can. Your printer may allow you to print two pages side-by-side in 'landscape' orientation -- and you'll save on paper costs, too.

Reduce your inkjet costs by economizing on ink when you are able to do so. Make sure to keep your ink cartridge supplies ready for when you need to do high resolution printing.

It May Be Cheaper To Have A Print Shop Print Your Big Jobs

You may want to consider out-sourcing your big printing jobs as it may be cheaper to have a print shop print your big jobs than it is to buy a new cartridge to get the job done at home. Many places will allow you to place your order online, allowing you to pick up at your convenience or you can even have them mailed to you.

If you are not using your ink often, you may want to consider an ink cartridge case. This will keep the cartridge from drying out and will keep it free from dust and particles that can clog when it sits too long.

Ballistics in Forensics - Distinctive Markings on Shell Casings

When CSI's approach a crime scene such as a shooting, one of the evidences they look for are spent shell casings. A shell casing refers to the part of the cartridge that is scattered at the crime scene after the gun powder ignites and the projectile is gone. The shell casing, gun powder, primer, and bullet are collectively known as a cartridge. Shell casings many times are the only piece of evidence that the forensic firearms examiner has available to work with. It is fortunate that the shell casings contain distinctive markings that are the focus of the forensic examiner's investigation.

What does the forensic firearms examiner look for in shell casings?

They look for the following:

The indentation left by the firing pin:

A simple visual inspection at the base of the shell casing reveals the location of where the firing pin hit, telling the forensic firearms examiner whether the shell had a primer cup, as seen in center-fire cartridges, or had a primer along the perimeter of the base, as seen in rim-fire cartridges. Knowing the location of where the firing pin hit can shorten the list of possible firearms used in a crime.

Breechblock patterns:

The breechblock refers to the back wall of the firing chamber. When gun powder within the casing explodes and violently forces the projectile down the barrel, the casing is pushed back against the breechblock, thus leaving an indentation on the bottom of the casing.

Headstamps:

Headstamps refer to the information stamped into the metal portion of cartridge casings and shotgun shells at the time they are manufactured. These markings sometimes include the factory's initials or logo, the gauge or caliber, or the type of cartridge.

Extractor and ejector impressions:

Extraction is the process when mechanisms in semiautomatic and automatic firearms pull the next cartridge from the magazine clip and position it in the firing chamber. Ejection refers to the process when these same mechanisms remove the spent shell casing from the firing 308 lapua brass chamber and jettison it from the firearm. If you watch a lot of CSI, the metal parts that fly away from the side of a firearm are the shell casings that you see being jettisoned or ejected. Extractors and ejectors differ among firearms, leaving their own unique impressions and indentations on the sides of the shell casings.

Whenever you watch your favorite CSI TV show, you will have a better understanding of what Calleigh Duquesne, the forensic firearms examiner, looks for when she analyzes spent shell casings found at a crime scene.
