EasyCoder PL-Series Printer Programmer’s Reference Manual 119
Note: All commands must be terminated with a CR/LF (0x0D, 0x0A).
Actions and parameter names must be specified in lower-case. Parameter
values should be specified in lower-case unless the parameter value itself is
case sensitive, such as a printer’s WLAN eSSID.
Command Format
The formats of the get, set, and do commands are described in the
following sections.
getvar Command
Purpose: You use the getvar command to get the current value of printer
parameters. This command must be terminated by a CR/LF (0x0D,
0x0A). The printer responds with the parameter value of “?” if the
parameter does not exist (usually due to incorrect spelling of the parameter
name) or it has not been configured yet. The parameter name should be
specified in lower case.
Format:
getvar “{ parameter name }”
where:
{parameter name} The name of the parameter to be retrieved. Please
refer to the parameter list for valid parameter names.
setvar Command
Purpose: You use the setvar command to set parameter values in the printer. This
command must be terminated by a CR/LF (0x0D, 0x0A). The parameter
name must be in lower case. Parameter values must be specified in lower
case, unless the parameter value itself is case sensitive, such as a printer’s
WLAN eSSID.
Format:
setvar “{ parameter name }” “{ value }”
where:
{parameter name} The name of the parameter to be set. Please refer to the
parameter list for valid parameter names.
{value} The new value to assign to the specified parameter
above.
