continuous media Label or tag-stock media that does not have
gaps, holes, notches, or black marks to indicate label separations.
The media is one long piece of material wound into a roll. This allows
the image to be printed anywhere on the label. Sometimes a cutter is
used to cut apart individual labels or receipts.
Contrast this with black mark media or gap/notch media.
core diameter The inside diameter of the cardboard core at the
center of a roll of media or ribbon.
diagnostics Information about which printer functions are not working that is used for troubleshooting
printer problems.
die-cut media A type of label stock that has individual labels stuck to a media liner. The labels may be
either lined up against each other or separated by a small distance. Typically the material surrounding the
labels has been removed. (See non-continuous media.)
direct thermal A printing method in which the printhead presses directly against the media. Heating the
printhead elements causes a discoloration of the heat-sensitive coating on the media. By selectively
heating the printhead elements as the media moves past, an image is printed onto the media. No ribbon is
used with this printing method. Contrast this with thermal transfer.
direct thermal media Media that is coated with a substance that reacts to the application of direct heat
from the printhead to produce an image.
dynamic RAM The memory devices used to store the label formats in electronic form while they are
being printed. The amount of DRAM memory available in the printer determines the maximum size and
number of label formats that can be printed. This is volatile memory that loses the stored information when
power is turned off.
fanfold media Non-continuous media that comes folded in a rectangular stack.
Fanfold media is either gap/notch or black mark media. Contrast this with roll media.
firmware This is the term used to specify the printer’s operating program. This
program is downloaded to the printer from a host computer and stored in FLASH memory. Each time the
printer power is turned on, this operating program starts. This program controls when to feed the media
forward or backward and when to print a dot on the label stock.
FLASH memory FLASH memory is non-volatile and maintains the stored information intact when power
is off. This memory area is used to store the printer’s operating program. In addition, this memory can be
used to store optional printer fonts, graphic formats, and complete label formats.
Font A complete set of alphanumeric characters in one style of type. Examples include CG Times ™ , CG
Triumvirate Bold Condensed ™ .
