No, a scanner is an input device.

Ask a probation officer.
What does DPI refers to what?
DPI means Dots per Inch. The more DPI you have to work with, all else being equal, the nicer your work will look.DPI Stands for Dot Per Inch.It has no real meaning on a computer. It is used as a measurement for a printed image. It corresponds to Pixels on a computer screen, but usually there are 4 times more dots per inch on a print, than pixels per inch on your monitor.See fuller explanation at What_does_pixel_stand_for_in_digital_photographyDPI can also refer to the sensitivity of an optical or laser mouse.
Need help with a scitex Dolev 200 series imagesetter. The lasers won't put the image on the film and it will only allow pdf files. how do i make it able to work with all types of files?
The type of file to be output is determined by the RIP and some platforms required a "dongle" to enable them. The Mac RIP was PS/M and version 8.x was the last. The Brisque required a new password to allow different formats. The RIPs used to convert a postscript file into a CT file and a LW file that the Dolev could output. When you say "won't put the image on the film" do you mean any image? Can you produce an internal pattern from the control panel (which checks out the laser and modulator)? if yes, then we are back to the RIP. If no, then you should be getting a "Danger- Laser beam on" warning message. This means that the software has turned the laser on but the detector hasn't seen it (and you'll need to buy a new laser or power supply or, if you're lucky, a light detector). If you're not getting the warning and getting nothing on film, your chemistry might be dead or the Dolev filter may need to be changed. Officially you are not supposed to do it but it can be removed. Good luck.
Where does the waste in prepress industry goes?
Well, it's been almost ten years since I've been associated with prepress (in a different line of work now) but I can say that over the years, disposal of waste products has probably become less and less of a problem. The prepress industry has changed dramatically over the last 20 years - even the last 10 years probably. I say that it's become less of a problem because compared to years past, there are less "waste products" involved in prepress, as more and more of it is done electronically and digitally, and goes direct-to-press, with with litho presses that have DP capability, or directly to digital printing presses. Back when I first started in the traditional prepress industry back in the 1980's, you had film that was recycled for it's silver content, and also the spent photographic chemicals from the darkroom that also had some silver in it. Recyclers would actually pay you to take it all off their hands and they would make their money getting the silver out of it. Another area was in plating - the spent chemistry from the plateroom had to be sent out to special recyclers who would dispose of it since the chemistry was toxic. Nowdays prepress deals with digital files received from clients/customers, and most, if not all, proofing and printing is done digitally. When I ended my prepress career about ten years ago, we were at the point where all of our prep work, including proofing and plating/imposition was done digitally with PDF files. The only step that involved chemical waste was the plating process. The plate was made digitally on a Creo imagesetter DTP/RIP but at that point it still had to be developed and gummed for press. Printers at that time were just on the cusp of eliminating even that, and just going direct to press or to digital printing itself. So the "short answer" to this question is these days prepress waste is not really much of an issue anymore. The whole process nowdays involves very little physical material to create waste byproducts.
What are the electrical devices used in printing and their functions?
Printing press -- puts ink on paper Press control console -- adjusts press color balance and registration Wide-format or grand-format inkjet printers -- prints vinyl for vehicle wraps, scrim banner, mesh banner and large sheets of paper. Wide-format printers have carriages from 36" to 84" wide; grand-format are wider. Some of the widest grand-format printers are the Gandinnovations Jeti 5024 and the EFI VUTEk 5330, which take media 204 inches wide. (Fun facts about the big VUTEk: it's 28 feet wide. It weighs nearly three tons. It uses 50 amps of 220v power, which is the same as your kitchen range. The ink for it comes in gallon jugs, and you pour it into jars behind the printer. You need to file an environmental impact statement with the state when you buy a 5330 because the ink contains petroleum-based solvents--actually, YOU don't file the statement, EFI does it for you; they have lawyers who write these all the time. They give you a "roll lifter" when you buy the machine, and most people move the media around with a forklift. It takes four people to load media into the printer--two behind the machine to put the media in, the other two to catch it and pull it down. When you get it they send you a cabinet full of spare parts; if the machine breaks you call the 24/7 hotline (they supposedly have a person there on Christmas night, which may be tested soon because with my workflow I'll probably be printing on my VUTEk 3360 on Christmas night) and they tell you what part to replace. It comes with an engineer from the company who sets it up for you. It prints 2237 square feet per hour, and it probably costs about $700,000--based on the fact that a 3360 is $300,000 and the 3360 only uses 126" media.) Cutter -- cuts paper to programmed-in sizes Folder -- folds printed pieces as required by the job Collator and stitcher -- creates saddle-stitched booklets Perfect binder -- creates perfect-bound documents Pocket folder gluer -- converts diecut pocket folder blanks into finished folders Laminator -- encases printed pieces in a tough plastic shield Inspection booth -- produces light of the correct color and intensity to inspect work by Densitometer -- measures ink density to assure color accuracy Reach truck -- moves pallets of paper around the pressroom Platesetter -- makes plates in a "computer to plate" workflow Imagesetter -- makes film for plates in "computer to film" workflow Digital front end (also known as a RIP) -- controls platesetters and imagesetters Automatic imposition processor -- creates layouts on plates Light table -- used to hand-strip films Vacuum frame -- exposes plates and proofs Stat camera -- takes pictures of printed pieces so you can print more of them. This is a REALLY outdated piece of equipment, but in a lot of cases--such as when a letterhead someone's been using for 50 years comes in with the instruction "make the new ones EXACTLY like this" it's quicker to shoot the letterhead, strip it and plate it than it is to use your computer. Film processor -- develops film Plate processor -- develops plates Computer -- does too many things to mention Drum scanner -- produces better images than any of those "just as good as a drum scanner" flatbeds ever dreamed of. Air compressor -- source of compressed air for many printing machines Vacuum pump -- source of vacuum for many printing machines (note: all 40-inch and larger presses and many smaller presses use both compressed air and vacuum; really small presses usually only use vacuum) Diecutter -- cuts printing into special shapes like circles, credit cards, suitcases... Coffeepot -- keeps pressman awake when he has to work a double shift to get a job out before the last Friday of the month Those are just a few of the electrical devices used in printing.
