Why use a ink-jet printer to print photographs?
You don't say compared with what; it is quieter than a dot matrix and cheaper than a laser. Ink jets can print on wide range of media; plain paper, glossy photo paper even compact discs.
In the Western World the first printer was the printing press invented in the 1700's. This was a huge innovation since up until then, everything had to be hand copied. The printing press consisted of blocks with letters that could be arranged in a tray and then emptied to make a new page. It was first invented in China and was adopted and modified by Europe in the mid sixteenth century.
What is a CO2 laser engraver used for?
A CO2 laser engraver is a type of laser engraving machine that utilizes a carbon dioxide (CO2) laser to engrave or etch various materials. It is commonly used for precision engraving, marking, and cutting a wide range of materials, including wood, acrylic, glass, leather, rubber, plastics, and certain metals. The Co2 laser engraver machine emits a concentrated beam of light that evaporates or melts the surface of the material, creating intricate and detailed designs, patterns, or text.
CO2 laser engravers are popular in industries such as manufacturing, crafts, signage, jewelry making, and electronics. They offer high levels of accuracy and can produce both shallow and deep engravings, depending on the power and settings of the laser. The versatility of CO2 laser engravers makes them valuable tools for adding permanent designs, logos, serial numbers, or other markings onto various items.
A high speed printing device that primarily uses a laser and static electricity for attaching toner to paper. I believe it should really be called the static electricity printer! You see; the primary principle at work in this machine is static electricity. The laser inside the printer never really touches the paper.
The LASER printer really has four basic parts that are most important.
1. The laser Unit (with mirror)
2. The Toner Hopper
3. The Drum Assembly (with 3 additional parts)
4. And the Fuser assembly.
How a laser printer is working:
1. Whenever the printer gets its information, the printers' circuit board then takes that information and converts it into a code. Like Morse code.
2. The laser prints it to a negative (statically) charged rotating drum.
3. when the laser pulses light on the drum it creates a small DOT of neutral electricity.
4. the drum or (toner hopper) charges the toner powder to a negative charge as well.
5. when the toner is pushed through the drum the toner is sucked into the Neutral spaces left by the laser. Creating an image.
6. paper is Positively charged. and pushed through the drum. The toner is statically bonded to the paper. Like a magnet, it sticks together.
7. the fuser assembly heats up 300+ degrees and fuses the toner to the paper.
Different from inkjet printers using ink, laser printers use toner as printing materials.
Ink cartridges are usually cheaper than toner cartridges. However, toner cartridge has the lower cost per page than inkjet does.
What is the role of a plotter?

in 1970-
1953
Well, to put computer information onto paper, to have a hard copy of the information in case a computer is not a viable option for the presentation of the information. Also for things such as Posters, flyers or handouts; which can be designed on a computer, but are not that useful on one.
What are the alternatives to a laser capsulotomy?
The alternative to laser capsulotomy is surgical capsulotomy
Types of printers and their examples?
Thermal - Like the old fax machines, uses a waxy paper heated to put an image on paper. Some portable printers use this.
Inkjet - Uses liquid ink put through little nozzles that are heated up and force the ink out onto the paper. Most popularLaser - Uses a laser beam on a photo sensitive film to attract toner (fine powder, no liquid here) and then puts the toner on the paper. Then the paper goes through a fusor to fuse the toner to the paper.Solid ink - Xerox only, uses wax based crayons to put an image on paper.Printing ink can be expensive, especially for high-quality or specialized inks. The cost of printing ink can vary depending on factors such as the type of ink, color, quantity needed, and the brand. It is important to consider the cost of ink when budgeting for printing projects.
The purpose of a laser iridotomy is to allow an equalization of pressure between the anterior (front) and posterior (back) chambers of the eye by making a hole in the superior peripheral iris
Can you print black and white without a color cartridge on a Kodak all in one printer?
no it is designed so it will not print without color cartridge having ink in it
Does cheap laser toner work as well as expensive toner?
"Yes, a cheap laser toner will work as well as an expensive toner. Make sure that the unbranded cartridge will fit your printer. Once installed, there should be no problem with the performance of the printer."
How do remove ink from thermal paper?
You will need nail polish remover, bleach (good bleach required- none of that 99 cent, watered down stuff), & a low or no lint rag (I used an old sock, right side out). First dip your rag in the nail polish remover & wipe over the ink you want to remove IN ONE DIRECTION ONLY. Yes, the thermal paper WILL turn black, but stay with me here. Next, using a different part of your rag, dip into the bleach- again, wiping IN ONE DIRECTION ONLY- & wipe your paper. If any of the ink you want to remove still remains wipe with nail polish remover again (you will not need to wipe with bleach again). You can start with the bleach first, but I find the paper is less likely to tear or nap if you start with the polish remover. Above all, BE GENTLE. You will want to practice before starting in on the real deal-- Walmart receipts are great for practice.

What is advantage and disadvantage of key frame animation?
It makes our posture bad and makes a skeletal body
What is the best print width range for label printers?
The best print width range for label printers depends on the specific application and the size of the labels required. Generally, label printers have a range of print widths that can vary from 1 inch to 4 inches or more.
For small labels, such as those used for address labels or product labeling, a print width of 1 inch to 2.5 inches is sufficient. For larger labels, such as those used for shipping labels or signage, a print width of 4 inches or more may be necessary.
When selecting a label printer, it's important to consider the specific needs of your application and to choose a printer with a print width that will allow you to produce the sizes of labels you require with high quality and accuracy.
What color does red and green make?
Brown or gray depending on if you are using true complementary colors or not. If you mix cadmium red (red-orange) with phthalo green (blue-green) in a ratio of 3 to 1, you will get a dark gray. If you look on the color wheel, you will see that red-orange and blue-green are directly opposite each other so they are true complementary colors.
If you use the same cadmium red and mix it with sap green (yellow-green) you get brown. The color wheel shows that they are on color away from being complementary, thus the brown instead of gray.
Adding white to either of these will give you varying shades of gray or light brown. There are two related links which may be helpful. The second is a video demonstration.
Alternative AnswerAll the above answers deal with pigments and paints. When dealing with light, the story is different. Red light added with green light in the right proportion makes yellow light.The area of your eye that detects color is called the "cone". Your cones are specialized to send the messages for "red", "blue" and "yellow" to your brain. The absence of red is green, just like the absence of white is black. Thus, under normal conditions, there's no way to combine red and green. However, there are very specific conditions that cause your retinas to receive both a "red" and a "green" signal and send both signals to your brain, resulting in "reddish green". Doing so is difficult, one has to flash red and green in quick succession before the person trying to see reddish green while trying to keep that person's head very still so not to disrupt the illusion.
When you blend red light and green light of equal luminance, they cancel out. Since most forms of light contain RGY, most people see yellow rather than white when this "cancel" happens. The reason why green and red paint turns brown is because you've overloaded the paint with pigments, it's absorbed so much over every color that it can't display yellow or white, but your eye is canceling out either the red or the green (as well as the blue or the yellow) because you can't normally see both at once.
Depends whether you mean pigments as in paint or colours of light.
Mixing red and green paint produces a sort of brown colour depending on the shade of the paints.
Red and green light produce yellow, which may seem strange, but true.
Where can a person go to get information on screen printers?
Screen printing information can be found on various websites. Respect Printing is a website run by a group of people dedicated to performing screen printing jobs. Their homepage offers detailed information on screen printing.
What is the voltage of line voltage?
It varies from country to country. In the USA it is 110 volts, in the UK it 230 volts +/- 10%/6%. In practise in the UK it is 240s volt +/- 6%, the slightly odd looking specification allows harmonisation with rest of Europe. In all these cases, the mains voltage is supplied AC (alternating current) and the voltage is given as root mean square (RMS). The peak voltage in the UK is 384 volts.
Striking paper, also known as friction paper, is a type of paper embedded with a special coating that ignites when struck against a rough surface. It is commonly used in safety matches, where the friction generated by striking the match head against the coated strip on the box ignites the match. This type of paper is designed for easy ignition and is crucial for the functionality of various fire-starting devices. Its unique properties make it a valuable component in creating reliable ignition sources.
