PY Then
17
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 characters 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 processed.
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 control 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. after 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 sent to the
current emulation.
A few fundamental GPL commands and concepts are described in the
following sections. Knowledge of these commands and concepts is essential
for understanding the descriptions and examples in the remainder of this
manual.
