Printers are machines that take information from a computer screen and put it onto a piece of paper. This can be text, say from a typed document, or graphics, like images from a digital camera. Originally, this was all that could be printed, but now, anything seen on a computer screen can be printed, allowing users to make newspapers, wedding invitations or even mixed-media paintings. Of course, like a pen needs ink to write, a printer needs something to put on the paper, and in the printer’s case it’s either printer ink or toner.

Toner is a black powder that bonds to paper when heated, so pages printed from these printers come out warm. Photocopy machines commonly use this process as well. You may have noticed warm photocopies in the past. Printers that use toner are called laser printers. Here, a laser draws an image onto a printing drum. This drum attracts toner from a cartridge and rolls the toner onto a piece of paper. These printers tend to be more expensive than printers that use ink, however, the cost per page printed is significantly less in this method. This is the advantage of using toner. When these printers run out of toner, the cartridge is replaced with a new one, and the old cartridge is sent in for recycling. Refilling a toner cartridge is generally not done. In the past, toner was refilled by pouring the powder directly into the machine, but it was very mess and most printers use cartridges now. Due to their cost-effectiveness, laser printers using toner are generally used in businesses that create a large number of documents.

Printers that use ink are called ink-jet printers. Here, an ink cartridge moves from side to side and shoots out ink onto the paper. These write text or draw a picture line by line. Usually, these printers have one ink cartridge for black ink, and another for magenta, yellow and cyan (or blue) ink, allowing full color printing. When the cartridges run out of ink, they need to be replaced or refilled with printer ink. However, some manufacturers do not recommend refilling used cartridges. Ink-jet printers are generally good for home use, excelling in printing out digital pictures. Though ink-jet printers are very inexpensive, the cost of printer ink can add up quickly if high volume printing is required.

To summarize, there are two types of printers – ink-jet printers that use ink cartridges, and laser printers, which use toner cartridges. Knowing which type of printer you have will tell you what you need to purchase. Or, just write down the make and model of your printer, bring it to an office supply store, and they will bring you what you need.

Toner is used in ink jet printers and copy machines in order to form the images that are created on the paper. It’s a powdery substance made from carbon and other polymers based on the specific ingredients determined by each individual manufacturer. In newer printers and copiers, toner is extracted from a cartridge that is inserted into the machine and applied to the paper as directed by the processing unit. For older machines, the powder is manually transferred from the packaging container into a reservoir in the unit. The powder is then extracted from the reservoir through the printer ink jet machine and ultimately ends up on the paper in the form of the desired images.

Sensors on the printer can determine when a toner cartridge needs to be replaced or when the reservoir needs to be refilled. The printer will not function properly without a sufficient amount of ink to complete the job. It’s very simple to replace a toner cartridge. Generally, when the machine indicates that the powder is running low, it’s possible to prolong the life of the printer ink cartridge by removing it from the machine, gently shaking it to gather the powder inside, and placing it back into the cartridge housing. For the older machines, refilling the reservoir is the only way to allow the printer to function again.

The combination of carbon and the other polymers is mostly harmless; however, when dumping the powder from the packaging into an older machine, the powder can linger in the air and can be ingested through normal breathing. While there are generally no immediate effects, prolonged exposure can lead to potential respiratory disease, which is why it’s necessary to handle the toner with care.

When replacing the ink in any machine, it’s a good idea to be cautious, to avoid banging the cartridges against anything, and to move slowly. It can stain clothing and skin if it’s not washed off in a moderate time-frame after making contact. Use cold water to remove ink from skin. For clothing, wash articles in a washing machine using the cold cycle. Warmer water will cause the powder to bond to the clothing.

To discard of the toner cartridges, it’s important to recycle and keep the packaging separate from regular waste. Many manufacturers will offer a discount or rebate on a refill if the used cartridge is returned or exchanged when purchasing a new one.

Toner is currently the most widely used form of printing words and images in both color and black ink from processor to paper. Industrial sized toner cartridges are made for businesses, larger printing, and copying machines while smaller units are made for personal and home use.

No matter how careful you are, at some point you’ll probably get a printer ink stain on your hands or clothing. Especially if you are changing laser toner or refilling ink cartridges. Here are some tips on removing printer ink stains from your clothes and skin.

Laser Toner Stains

The ink in toner cartridge is actually a fine powder. It can be washed off your skin with cold water. DO NOT use warm water, as the heat will make it sticky and stain your skin! Then you’ll have to use some abrasive hand soap, or just wait for the stain to fade. If you get toner on your clothes, try to brush it off with a broom or other type of dry brush or cloth. You can also try shaking it out. Chances are, however, it will stain permanently. You can try washing it individually in cold water, but this is not a sure fire solution. ALSO DO NOT VACUUM UP LASER TONER: Laser toner is static-charged, and could cause a fire in your household vacuum.

Printer Ink Stains

Most printer ink will wash off the skin. Use some abrasive soap or rubbing alcohol for tougher stains. If you get some on your clothing, dab it with rubbing alcohol and then blot it with a dry towel. This should remove most of the ink. This works well for carpet stains too. You can also try spraying the stain with some cheap hair spray prior to washing it in the washer. Over the counter stain-removers will also work. The bottom line is, just be careful.

It can be scary shopping online. You never know who really is on the other side of that computer screen. You don’t get to meet them. Talk to them.

- Compare Price: We’re all worried about the bottom line. So, you can choose a retailer based strictly on the price of their ink cartridges and toner cartridges. However, be aware that they may not have very good shipping policies or return policies. Sometimes paying the least, isn’t always the best option.

- Shipping Costs: You may find an online retailer that has the lowest cost for the product, but then when you go to place the order, there are huge shipping and handling charges added on. So, be sure to check the shipping policies of the retailers. Many of them will offer free shipping on orders of a minimum value.

- Customer Service Policies: Its good to know that there are people on the other side of the computer screen, that know you will want the same level of customer service you find in the big box office retailers. Review their policies, and see how they can be contacted. Be it phone, email, or a 24 hour a day service line.

We walk into the meeting embarrassed and complain about the lack of new ink cartridges.
