jZebra & Epson TM-U220: Problems with bit image commands (ESC *)

[adrian hurtado]

Hi,

I'm a newbe with jzebra. Now I can print a receipt using the sample.html with the modifications shown in http://code.google.com/p/jzebra/wiki/ESCPCommands. But now I would like to print a logo using the bit image commands (ESC *). I'm trying to get work the example shown at ESC-POS-Programming-Guide.pdf that is the following:

Here is my code for m=0 and only 1 cycle instead of 5:

function print() {

  var applet = document.jzebra;

  if (applet != null) {

    applet.append("\x1B\x40"); // 1

    applet.append("Test begins\r\n");

    // ESC * command

    applet.append("\x1B\x2A\x00\x10\x00\x01\x02\x04\x08\x10\x20\x40\x80\x80\x40\x20\x10\x08\x04\x02\x01");  // only 1 cycle instead of 5, as the example

    applet.append("Test ends\r\n");

    applet.append("\x1D\x56\x41"); // 4

    applet.append("\x1B\x40"); // 5

    // Send characters/raw commands to printer

    applet.print();

  }

  // *Note:  monitorPrinting() still works but is too complicated and

  // outdated.  Instead create a JavaScript  function called 

  // "jzebraDonePrinting()" and handle your next steps there.

  monitorPrinting();

}

In the resulting receipt, the texts "Test begins" and "Test ends" are printed perfect, but no other character or pixel is shown in the middle. The bit map is simply ignored.

Has anyone got print ESC * bit image commands?

Thanks and regards,

Adrián

Sorry, I missed the image showing the example. Here you are:

Thanks

[Tres Finocchiaro]

Adrian,

Unfortunately all web browsers have problems with \x00 (null).  This is because the javaScript language terminates strings this way.

There is an appendImage example in the wiki that does the hex conversion for you.  Can you try this out?  Just give the URL of the image and the ESCP option.

Hi Tres,

Thank you for the answer. I have tried replace the line for ESC * commands for this one:

    applet.appendImage(getPath() + "img/image_sample_bw.png", "ESCP");

But then I get something like that:

    Test begins

    Test ends

    @EG 16 64 0 0 000000000000000 …. about 20 cm of lines of hexadecimal characters … 0000000

So I can't print any image.

[adrian hurtado]

Hi again Tres,

I've just resolved the problem encoding the ESC * commands in base64 as I have seen in other post.

Thanks

[Tres Finocchiaro]

Thanks for the update. :)

Hi. I'm using TM-U295 and not working printing images, neither example of jZebra 1.5.6.

Can you put the code that worked for you?

Thanks.

[Tres Finocchiaro]

Please try version 1.6.5 and see if that corrects your problem.

A sample has been provided with 1.6.5, just click the print escp image button.

I've downloaded it and does not work.
Perhaps the hexadecimal codes must be different to print image.
I attach the pages of the manual.

Thanks.

[Tres Finocchiaro]

Yes, there is no doubt that that syntax is different.

Can you try this:

qz.appendImage(getPath() + "img/image_sample_bw.png", "ESCP", 0);

This will replace the 33 with a 0 and should work for your printer.

And also for clarification in language syntax, can you link me the manual you are using?  If I can differentiate between this automatically using code, it would be nice.

For example, do you think that one version is ESCP2 and the other is ESCP?  If so, I could simply allow ""ESCP2" to switch this code-side so that the "single" and "double" still work.

Thanks for your interest but neither works.
I attached the manual I'm using.

Thanks for all your time and effort.

hi, some body have a example how to send image to tm-u220 ?

thanks for time and help

i try the using the method from sample.html but is not working

[Tres Finocchiaro]

hi, some body have a example how to send image to tm-u220 ?

Have you tried using a smaller image?  Some printers can't handle the width of our logo and you should try cutting the image in half and seeing if that prints?

-Tres 

[Arnaldo Rafael Gonzalez Jimenez]

hi, tres thanks for time and help. i am testing the TM-U220 using the sample.html

when i hit print the printer prints strange characters

[Arnaldo Rafael Gonzalez Jimenez]

Test one

qz.appendImage(getPath() + "resources/images/logos/cpago/1.bmp","ESC *",0);

result : windows-1252 image conversion is not yet supported

Test two

qz.appendImage(getPath() + "resources/images/logos/cpago1.bmp","ESCP", "single");

result: prints strange characters

image: 

dimension 250x50

Bit Depth 8

[Arnaldo Rafael Gonzalez Jimenez]

new image:

image: 

dimension 250x50

Bit Depth 1

[Tres Finocchiaro]

It may be an incompatibility with your printer.  If you can find an example of the image command, we can add support for your printer, but I'm very surprised it's not working.

Can you try with a very small image (i.e. 64x64) and use PNG as to remain constant with our sample.html.

Also, I'm not suure where the "ESC *" command comes from.  Despite the misleading error message, that's not an available choice for appending images, it should be ESCP.

https://code.google.com/p/jzebra/wiki/TutorialWebApplet#Printing_Images

Note that the while() syntax is bad and is deprecated, continue to use qzDoneAppending approach instead.

If is is indeed a compatibility issue, please help find a proper ESCP image example for your printer, we can add the necessary functionality to the applet.

hi, Tres i test using a small image

64x64 PNG

1 - bit depth

qz.appendImage(getPath() + "resources/images/logos/test/3.png","ESCP", "single");
qz.appendImage(getPath() + "resources/images/logos/test/3.png","ESCP" );

same result

Which OS are you using?  Also, is your printer setup according to our setup guide (as a raw printing device?)

EPSON TM-U220PD
Model 188D

1 - Connected to LTP1

2 - Generic/Text print driver

3 - Rename to ZEBRA

4 - Share print as ZEBRA on the network

5 - net use LPT1 \\pcprinter\ZEBRA

this is my configuration in this moment!

[Tres Finocchiaro]

I'm confused.... Why are you sharing it on the network if you have it connected locally?

You should be able to add a local port pointing to LPT1.  Sharing it on the network is only necessary if you have an old program which is hardcoded to LPT1.

[Arnaldo Rafael Gonzalez Jimenez]

my pc don't have lpt1 port 

[Tres Finocchiaro]

I'm not sure what you mean.  Why are you using LPT1 to begin with?  Are you testing your printing via command line?  There's very few reasons to use the legacy LPT1 handle.

- Tres.Fin...@gmail.com

[Arnaldo Rafael Gonzalez Jimenez]

ok, Tres again sorry for the troubles and problems and thanks for your time and help

1 - I tried printing from the PC that has the printer connected directly to the port LPT1( Same result)

2 - I enable console log and i see this

[Tres Finocchiaro]

@Arnaldo,

If image printing is not working then there must be a compatibility issue with your hardware.  If you can mail me incidental hardware, or provide ESCP image printing instructions for that printer we can proceed to fix it in the print applet.  We currently test on the TM88 series printers, so the TM-U220 must have some compatibility differences (I'm very familiar with the TM-U220 hardware, but have never tried printing to it from qz-print before).

Otherwise, you may find a conversion utility which prepares the bitmap data for your in the correct format (use base64 encoding so that JavaScript is happy), and then use append64(), which the applet does currently support.

[Arnaldo Rafael Gonzalez Jimenez]

thanks Tres for your help

I think the problem is that the TM88 is thermal and the TM-U220 is point matrix

i will test the append64

[Tres Finocchiaro]

@Arnaldo,

I'm looking up the specs on this printer and the print buffer is very small (40 bytes).

Can you try appending an image which is 32 pixels wide?  I looked up the specifications and I can't find anything that would suggest that our existing ESC * commands won't work on it.

-Tres

- Tres.Fin...@gmail.com

[Arnaldo Rafael Gonzalez Jimenez]

Image

4.png

32x32 

bit depth 1

same result :(

using the command qz.appendImage(getPath() + "resources/images/logos/cpago/4.png","ESCP", "single");

attempt to base64?

[Tres Finocchiaro]

You can use base64, but without the appropriate image commands, you'll only get text on the paper.

- Tres.Fin...@gmail.com

[Arnaldo Rafael Gonzalez Jimenez]

I will continue investigating 

thanks for all your time

same error with epson tmu220 - testing with posted images and same result, the printer only prints unknow caracters :(

[Tres Finocchiaro]

After several emails, it is my belief that our image commands are incompatible with the TM U220 series printers.  We'd be happy to offer support for this if we can obtain a programming guide with the proper commands.

If you need it right now, change the code and recompile for your own needs.

[chechovr]

thanks... ill' wait for the next version (update)... and thanks again for ur time..... its the best software!!
