Reading the Printer’s Status
9. Label Length
10. Gap Length
11. Media Light Transmission
The presently set label length, as specifi ed by the printer’s setup, is
returned by the following instruction:
? SYSVAR
(<parameter>)
<parameter> = 2
returns label length in dots
The actual label length, as measured and set by a
TESTFEED
command, is returned by the following instruction:
? SYSVAR
(<parameter>)
<parameter> = 100
returns label length in dots
Note that the SYSVAR (2) value must be equal to or exceed the
SYSVAR (100) value, or the labels will be truncated.
The presently set label gap length, as set by a
TESTFEED
com-
mand, is returned by the following instruction:
? SYSVAR
(<parameter>)
<parameter> = 101
returns label gap length in dots
The light transmission of the media in the LSS is returned by
the following instruction as a value in the range 0-31, where
0 is maximum refl ection/transmission and 31 is no refl ection/
transmission. It can be used to assess the translucency of labels
and liner and also has the side-effect of waiting until the motor
stops.
? SYSVAR
(<parameter>)
<parameter> = 1
returns the light transmission value
