Problem Printing use Esc/Pos command

[99]

Dear all,

I have been failed so many times to use esc/pos command to set raw printing style.
I used esc commands based on  http://www.delfi.com/SupportDL/Epson/Manuals/TM-T88IV/Programming%20manual%20APG_1005_receipt.pdf
especially i need to use esc commands as follows
    ESC a : Select justification (center & right)
    ESC d : Print and feed n lines
    /t         : tab

but I do not understand why the esc command did not work, how to set n variable?
Could you please show me the right way?i would be glad if you can give me an example

this is my code before:
function print() {
         var applet = document.jZebra;
         if (applet != null) {
       
        applet.findPrinter("zebra");
        applet.append("\x1B\x40"); //reset printer
        applet.append(chr(27) + 'w1' + chr(27) + 'W1' + chr(27) + chr(69) + "company\r\n" + chr(27) + 'w0' + chr(27) + 'W0');//Format Bold on
        applet.append("address\r\n" + chr(27) + chr(70));//Format Bold off
        applet.append("Telp\r\n");
        applet.append("\n");      
        applet.append("Cashier '\r\n");
        applet.append("------------------------------------------\r\n");
        applet.append("Date\r\n");
        applet.append("Item \t Price \t Qty \t Disc \t Total \r\n");
        applet.append("---------------------------------------- \r\n");
                 
                           
        applet.append("------------------------------------------\r\n");
        applet.append(chr(27) + chr(97) + chr(2));//right alignment
        //applet.append(" SUB TOTAL : \t 3750\r\n");
        //applet.append("TAX   : \t 5000\r\n");
        applet.append(chr(27) + chr(69) + " TOTAL     : \t 5000\r\n" + chr(27) + chr(70));
        applet.append("CASH   : \t 5000\r\n");
        applet.append(" CHANGE   : \t 5000\r\n");
        applet.append(chr(27) + chr(97) + chr(1));//center alignment
        applet.append("-THANK YOU-\r\n");
        applet.append("\x1B\x40");
        applet.append(chr(27) + chr(100) + chr(5));//feed paper 5 lines
        applet.print();// Send characters/raw commands to printer
     }
     
     monitorPrinting();
      }

Hello,

For centering, try:

 applet.append(chr(27) + chr(97) + chr(49));//center alignment  

chr(49) is actually 1 where as chr(1) is SOH.

Similar to the other functions that needs those "n" integers. Check ascii table here: http://www.asciitable.com/

Bahadir

Dear Bahadir,

Thank you for your responce.
I have tried to change:

function print() {
         var applet = document.jZebra;
         if (applet != null) {
       
        applet.findPrinter("zebra");

        applet.append(chr(27) + chr(97) + chr(49));//center alignment

        applet.append("-THANK YOU-\r\n");
        applet.append("\x1B\x40");

        applet.print();// Send characters/raw commands to printer
     }
     
     monitorPrinting();
      }

and it did not work :(

regards,

Candra

I cannot provide ESCP help in this case, but I'd like to add that "ESC a" can be represented as:

"\x1B" + "a"

or

"\x1Ba"

or

String.fromCharCode(27) + "a".

The CharCode or the Hex is only needed when it's a special character.

Eko is also a great resource on this topic, he wrote "directprint" for these ESC/P difficulties. Perhaps it can help?

Hello Candra,

I have just tested it with my good old TM-T70 and the following command is outputting this.

applet.append("\x1B\x40");

applet.append("\x1B\x61\x31");//center alignment 

applet.append("-THANK YOU-\r\n"); 

applet.append("-TEXT TEXT TEXT-\r\n"); 

applet.append("-XXXXXXXXXXXXXX-\r\n"); 

applet.append("\x1D\x56\x41");//cut

If this doesn't work, I suggest trying the printers own driver instead of a generic driver.

Check the following documentation if you haven't seen it before.

P.S: Sorry for the late response, though I have sent this yesterday, seems google-groups rejected my email with an attachment.

Regards,

Bahadir
