SPECIAL PRINTER CONTROL CODES

The following control characters perform special functions. All other control characters are
ignored. Some of these instructions are also accessible through a ^D sequence.
^A Accumulator Mode: Used to supply parameters for ^D commands. These parameters
must be positive integers and are generally decimal numbers but they can be binary if
preceded by a ASCII B. (i.e., ^AB00000001^D215 equals ^A1^D215)
^B Text Entry Mode: Instructs the printer to enter text entry mode. This command (or ^D25)
must be sent before the text information. This command is equivalent to ^D25 but does not
require a 5 after it (ie. ^Btext data string5). Because control B is shorter than ^D25, it is
easier to use in direct terminal mode. In general it is better to use ^D25 inside a file or
program.
^C Print a label: Prints a single label or starts printing a batch of labels. This command is
equivalent to ^D35 but does not require a 5 after it. Because Control C is shorter than
^D35, it is easier to use in direct terminal mode. In general it is better to use ^D35 inside a
file or program.
^D Command Mode: Used to issue commands to the printer. This command is normally
preceded by a ^A sequence (see above).
^E Printer Enquiry: See section 5.2 for more details (equivalent to ^D55 but does not require
a 5 after it). Because Control E is shorter than ^D35, it is easier to use in direct terminal
mode. In general, it is better to use ^D55 inside a file or program.
^M Terminate Text or Data String: Must be used to terminate a text or data string. (Same as
a carriage return or enter key on computer keyboard)
^H Deletes The Last Printable Character Entered: This is used only when communicating
to the printer through the keyboard. (Same as Delete key on computer keyboard.)
^K Print Test Label: A test label consists of a series of diagonal lines. It is useful in
determining the condition of the dots on the printhead (equivalent to ^D115).
^L Print Blank Label: (Equivalent to ^D125)
^Q XON: Instructs the printer to continue sending data.
^S XOFF: Instructs the printer to stop sending data.
