Code 128
A very high density alphanumeric symbology that supports the extended
ASCII character set. It is a variable length, continuous code that uses multiple
element widths. Code 128's high density makes it useful when printing data in
a limited space. Its maximum density is 12.1 alphanumeric characters per inch
or 24.2 numeric characters per inch.
Code 16K
A two-dimensional (stacked rows), ultra-high density bar code symbology. It is
based on Code 128 and is used widely to label unit-dose packaging for the
healthcare industry.
Code 39
A discrete, variable length, and self-checking bar code symbology. The
character set is uppercase A to Z, 0 to 9, dollar sign ($), period (.), slash (/),
percent (%), space ( ), plus (+), and minus (-). Code 39 can be extended to the
full 128 ASCII character set by use of a two-character encoding scheme (see full
ASCII). Its maximum density is 9.8 characters per inch.
Code 49
A multirow symbology for high data density. The last character in each row is
used for row checking and the last two characters of the symbol are used for
overall checking. The character set includes all 128 ASCII characters. Its
maximum density is 93.3 alphanumeric characters per inch or 154.3 numeric
characters per inch.
Code 93
A variable length, continuous bar code symbology using four element widths.
It can be used interchangeably with Code 39 when higher density printing is
required. The character set is the same as Code 39. Its maximum density is 14.8
characters per inch.
cold boot
One of two ways to boot the device; compare to warm boot. A cold boot
invokes the BIOS boot sequence, which verifies that the 256K flash system
image is not corrupt, clears all memory, and performs a complete power-on
self test (POST) to ensure that the hardware and peripherals are operational.
The cold boot initializes the system hardware for use by system software, loads
the default configuration, runs AUTOEXEC.BAT and CONFIG.SYS, and loads
DOS. Because the physical RAM drive is initialized, all files on drive E are lost.
You may cold boot the device to clear the conventional memory, break out of
an application that is locked in an infinite loop, or recover from an error
condition.
