Question
When do you need to select
the active sheet with GS ( G
function 80?
A check is automatically
selected as the active sheet
with FS a 0, read check
paper; however the check is
not selected automatically
by GS ( G function 65
when reading an image of
a check. Why?
What is the difference
between GS ( G function
48, select slip as the paper
type and the side of the
sheet to be printed,
ESC c 0, select paper
type(s) for printing?
Before image scanning you need to select a
check as the active sheet.
The current command, FS a 0 has multiple
functions so that it automatically selects the
active sheet; then reads the MICR; however GS
( G function 65 has only one function so that
there is flexibility of command combination,
which follows the policy of the ESC/POS that
one command has one function.
Print sheet and print side to be selected are
different. GS ( G function 48 is exclusively for
a slip, selecting surface or back of the sheet,
not for selecting roll paper. After executing FS
a 0, read check paper, even if GS ( G function
48 is executed, the slip will not be ejected;
therefore, it is possible to check the single-pass
processing.
and
ESC c 0 can select roll paper or the surface of a
slip; however the back of the slip cannot be
selected. After executing FS a 0, read check
paper, if the slip is selected by ESC c 0, the slip
is ejected and the printer will be in the slip
insertion waiting state.
