When Graphics Mode is on:
•The control panel displays ONLINE GRAPHICS
•All GPL commands and data are processed by Code V
•Non-GPL data is passed to the current emulation.
PY Then
This control panel option defines the action taken on character s that are on
the same line as the Graphics Mode On Command (^PY ). The options are All,
Term, and None. The default is None. These options are defined as follows:
All: All data following Graphics Mode On Command is processe d.
Term: Only the Terminator (FF, LF, or CR) is processed.
None: None of the data is processed.
If the None option is selected, any one of the following contr ol codes (or
combination of control codes) immediately following a ^PN or
^PY^- on the same line will not be printed:
•Carriage Return
•Line Feed
•New Line
•Form Feed
•Carriage Return followed by a Line Feed
•Carriage Return followed by New Line, or Carriage Return followed by
Form Feed
If PY Then is set to All or Term, all characters that follow a PN or ^PN^- on the
same line will print.
Turning Graphics Mode Off
The Graphics Mode Off Command is the sequence ^PN followed by a Pass
Terminator. As with the Graphics Mode On Command (^PY), the Graphics
Mode Off Command must be sent in the first column of a line (i.e. a fter a
Carriage Return). This command will cause the printer to:
•Exit the Graphics Mode
•Display the ONLINE message
•Treat all further GPL commands as printable characters to be s ent to the
current emulation.
A few fundamental GPL commands and concepts are describ ed in the
following sections. Knowledge of these commands and c oncepts is essential
for understanding the descriptions and examples in the rem ainder of this
manual.
