9.6 Error Messages in HP-GL Command Mode
If any of the HP-GL command error messages listed in the following table is displayed, the cause can
nearly always be traced to one of the causes below:
• The software application’s output device setting has changed; or
• The plotter’s interface conditions have changed.
If a command error occurs while the COMMAND setting is HP-GL, therefore, rst check the two
corresponding points below.
• Congure the software to drive your plotter and ensure that the software’s interface conditions are
correctly set; and
• Re-specify the plotter’s interface conditions.
