9.3.3 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:
(1) The software application’s output device setting has changed; or
(2) The plotter’s interface conditions have changed.
If a command error occurs while the COMMAND setting is HP-GL, therefore, first check the two corre-
sponding points below.
(1) Configure the software to drive your plotter and ensure that the software’s interface conditions are
correctly set; and
(2) Re-specify the plotter’s interface conditions.
Solution
Issue a command that the plotter
will recognize.
Re-issue the command with the
correct number of parameters.
Re-issue the command with its
parameters specified within their
permissible ranges.
Specify a character set that the
plotter will recognize.
Issue the command with its coor-
dinate data specified within the
effective cutting/plotting area.
Increase the buffer size.

Cause
An unrecognizable command was
issued.
A command was issued with the
wrong number of parameters.
A command containing an invalid
parameter was issued.
An unknown character set was
specified.
A command was issued with coor-
dinate data that exceeds the effec-
tive cutting/plotting area.
The data being input exceed the
capacity of the downloadable char-
acter buffer, polygon buffer, etc.
While executing an output com-
mand, the plotter received another
output command.
Receipt of the ESC character was
followed by an invalid byte.
A device control command con-
taining an invalid byte was received.
An I/O control command was is-
sued with parameter outside of the
permissible numeric range.
An I/O control command was is-
sued with too many parameters.
During data transfer, a framing error,
parity error, or overrun error oc-
curred.
The I/O buffer received data faster
than it could process the data.
