Epson TM-L60 Operator's Manual page 63

The 12 characters, "012345678901" are print data.
A check-digital is added by the printer because 12 characters are sent, and
"012345678901" is printed.
"CHR$ (0)" must always be used as the last command (representing end of
data.)
Using the drawer kick-out
350 PRINT #l, CHR$(27); "P"; CHR$(0); CHR$( 10); CHR$( 100);
The "p" generates a specified pulse; Refer to ESC p
In line 350, the module terminal of the drawer kick-out outputs a 20 ms pulse
followed by a 200 ms wait.
How to read the status of the drawer kick-out
360 PRINT #l, CHR$(27); "u"; CHR$(0);
370 A$ = INPUT!$(l, #l)
380 IF A$ = CHR$(0) THEN PRINT "DRW: L"
380 IF A$ = CHR$( 1) THEN PRINT "DRW: H"
The "u" command in line 360 transmits the status of the drawer kick-out to
printer. Refer to ESC u
370 receives the data from the printer through RS-232C.
