CX208/212 Programming Guide
2.If you are using the printer’s RS232 interface, it is necessary to set the COM port on the PC such that the CTS and DSR signals will be ignored. Send your OPEN “COM” statement in the following way:
OPEN “COM1:9600,E,8,1,CS,DS” AS #1
This sets the RS232 communication parameters of the host PC’s COM1 port for 9600 baud, Even parity, 8 Data bits, 1 Stop bit and directing the port to ignore the CTS and DSR control signals.
3.You may want to minimize keystrokes and program size by assigning the <ESC> character to a string variable since this character is used quite often.
The following two examples in BASIC show a typical example using these hints. Both of these examples use the Standard Protocol codes.
Printing with the Parallel Port
5 | REM Parallel Example | Identifies the program as a parallel 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$” string as an <ESC> |
|
| character |
20 | WIDTH “LPT1:”,255 | Sets the width of the output to 255 |
|
| characters |
30 | LPRINT E$;"A"; | Sends an “<ESC>A” command code to |
|
| the LPT1 parallel port |
40 | LPRINT E$;"H400";E$;"V100";E$;"WL1SATO"; | Sends the data “SATO” to be to be |
|
| placed 400 dots horizontally and 100 |
|
| dots vertically on the label and printed in |
|
| the “WL” font. |
50 | LPRINT E$;"Q1"; | Instructs the printer to print one label. |
60 | LPRINT E$; “Z”; | Tells the printer that the last command |
|
| has been sent. The printer can now |
|
| create and print the job. |
Printing with the RS232 Port
5 | REM RS232 Example | Identifies the program as a RS232 port |
|
| print label. The “REM” prevents this data |
|
| from being sent to the printer and |
|
| displays it only on the screen. |
10 | E$=CHR$(27) | Sets the “E$” string as an <ESC> |
|
| character. |
20 | 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. |
