ASCII – American Standard Computer Information Interchange. A character encoding scheme that was developed in the 60s. The first ASCII character set was published in 1963. The control language was used as a control language for teletype machines and was based off of telegraph codes, then further updated for more modern devices. ASCII codes were used to represent text in  computers and other digital equipment that use text. And was the most commonly used character encoding language used on the World Wide Web until it was surpassed by UTF-8 in 2007. Many modern encoding schemes are based on ASCII.

ASP – Active Server Pages.A technology that simplifies customization and integration of Web applications.

B

Bar Code – The familiar pattern of vertical lines found on many products used for inventory, identification and encoding other useful information. This technology is used in document imaging to provide a means of increasing the speed in which documents can be cataloged for archiving.

Batch Processing – Inputting a large amount of information in a single step as opposed to dividing up the job.

Bates Stamping – Used primarily in the legal field for stamping images and documents with date & time and other information as they are scanned or processed. Some scanners, copiers and MFPs will have Bates Stamping available as an option. Named after the Bates Automatic Numbering-Machine or Bates stamper invented by Edwin G. Bates in the late 19th century.

BCC – Blind Carbon Copy. Used when adding sending email but you don’t want the recipient to show up on the distribution list. Since you never know who might be BCC on email you receive, be cautious when using the “reply to all” option. You might send information or comments to someone unknowingly.

CMYK – Cyan Magenta Yellow Black. The CMYK color model is a subtractive color model, used in color printing. Colors are reproduced using Cyan, Magenta, Yellow, and Black colored toner or ink. This is the process used by copiers, printers, and MFP’s. As opposed to a computer monitor, smart phone, or other mobile device with a screen which use RGB (Red Green Blue). CMYK is subtractive because part of the spectrum of light is absorbed and you only see the colors which are reflected by the toner or ink. RGB devices project the colors you see instead of reflecting color. Because of the two different color models and technologies involved (CMYK & RGB) the colors on your screen are going to be different than what gets printed out of you’re copier, printer or MFP. Depending on you’re devices adjustments are made to correct for the difference in color models.

They are less likely to jam or mis-feed since originals are handled fewer times.

DTLS – Datagram Transport Layer Security.

Duplex / Duplexer – Printing on both sides of the paper. 2-sided copies. Many modern machines have this available since it was required for compliance with the energy star program. Printing on both side of your paper can reduce your paper usage by 50%. With the advent of stackless duplexing this feature is way more reliable than it used to be. Having a duplex unit on your machine also saves the time it would take to reload the paper in the machine to print on the other side.

Duty Cycle – Term used to describe the amount of pages which can be handled from a particular device (scanner, copier, printer, fax, MFP) calculated on a monthly basis. This is frequently overstated by manufacturers to be competitive with the other manufacturers overstated claims. Duty Cycle is not to be confused with the recommended monthly volume which is the amount of pages per month actually recommended by the manufacturer for the device. The recommended monthly volume is usually pretty close to what the device can realistically handle on a monthly basis. Here is an example, XYZ Printers Duty Cycle is 120,000 pages per month, actual recommended monthly volume for the same printer is 4,000 pages per month.
