PRINTING WITH THE RS232C PORT
5 REM CL612 Parallel Example Identifies the program as a CL612e RS232C port print
label. The “REM” prevents this data from being sent to the
printer and displays it only on the screen.
10 E$=CHR$(27) Sets the“E$”string as an <ESC>character.
OPEN “COM1:9600,N,8,1,CS,DS”AS #1 Opens the COM1 port for output and sets the parameters
as 9600 baud, No parity, 8 Data bits, 1 Stop bit and
instructs the port to ignore the CTS and DSR control
signals.
30 PRINT #1,CHR$ (2); Sends an <STX> (ASCII Code a decimal “2”) to the printer
instructing it to prepare to receive a message.
50 PRINT #1,E$;"A"; Sends an “<ESC>A” command code to Print Port #1
opened by statement 20 above.
60 PRINT#1, E$; "H400"; E$; "V100"; E$;
"XL1SATO"
Sends the data “SATO” to be placed 400 dots horizontally
and 100 dots vertically on the label and printed in the“XL”
autosmoothed font.
50 PRINT #1, E$;"Q1"; Instructs the printer to print a quantity of one label.
60 PRINT #1, E$; “Z”; Informs the printer that the last command has been sent
and printing can occur.
70 PRINT #1,CHR$ (3); Sends an <ETX> (ASCII Code decimal “3”) informs the
printer of message end.
Identifies the program as a CL612e RS232C port print
label. The “REM” prevents this data from being sent to the
printer and displays it only on the screen.
