Print to file is printing underlying html code not browser content, files overwritten. #157

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
WHi,

I need to print to file (no printer communications required) but keep the files 
in the folder automatically creating the file name based on +1 to base file 
name such as: 1000, next file 1001, next file 1002, etc. Currently new print 
replaces existing file.

I need to print the content of the HTML page that has only ascii text 
characters, ie: there is no rich text, images or html formatinng codes. See 
sample page content:
-----------------------
~PUERTO[1]
~DOCUMENTOFISCAL[]
~DOCUMENTOREFERENCIA[%ORDER_ID%]
~TIPODOCUMENTO[0]
~CAJA[001]
~SUCURSAL[100]
~RAZONSOCIAL[B&R]
~NCF[123456789%ORDER_ID%]
~RNC[%comprobante_fiscal%]
~PROPINA[SI]
~COPIAS[0]
<SHOP_BODY>~DETALLE[%SHOP_ORDER_ITEM_NAME%,%SHOP_ORDER_ITEM_COUNT%,%SHOP_ORDER_I

~CIERREDOCUMENTO[Gracias por su compra lo atendio %LOGGED_USER%]

------------------
But what happens is that that it appends all the underlying html file (like 
browser view source)

I want what is seen on the actual browser's page (above text content)

My current config is jzebra verion 1.5.6, windows XP

Using only:
document.jzebra.appendFile(window.location.href);
document.jzebra.printToFile("C:\\jzebra_test_nm.txt");

Any tips?
1- To keep ascii files, increase their name by n+1
2- Print view or div, not underlying code

Thanks

It could use some improvement, but this is what I put together:

<script>

var fileCounter = 0;
function printDivToFile(id, outputFile, ext) {
    if (document.jzebra != null) {
        document.jzebra.findPrinter(); // Needed due to a bug w/ NullPrintService
        document.jzebra.append(document.getElementById(id).textContent);
        document.jzebra.printToFile(outputFile +  pad(fileCounter++, 3, 0) + "." + ext);
    } else {
        alert("Error! jzebra is null.");
    }
}

function pad(n, width, z) {
    z = z || '0';
    n = n + '';
    return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
}

</script>

<input type="button" onClick="printDivToFile('test-div', 
'C:\\Users\\YOUR_USERNAME\\Desktop\\test-div', 'txt');" value="Print to 
Desktop, etc"><br />

<div id="test-div">~PUERTO[1]

Hi,

You are a genius!! thanks so much. I was able to implement the code and it is 
working quite well.

2 issues:

1- when I do the checkout in the online POS it goes to the confirmation page, 
as should, and this is where the raw "txt" content is placed (test-div) When I 
"print" it produces the file test-div000.txt as expected, but if the cashier 
hits the print button again, that will create file test-div001.txt and if you 
click "print" again we get test-div003.txt etc.

Now if we go back to the POS and create another sale and repeat the process we 
will overwrite ticket test-div000.txt

In other words the auto numbering is happening on re-printing (which we prefer 
not to) and not for each new transaction.

Can you further assist?

2-The file produced is encoded incorrectly, so instead of seeing:
~PUERTO[1]
~DOCUMENTOFISCAL[]
~DOCUMENTOREFERENCIA[%ORDER_ID%]
~TIPODOCUMENTO[0]
~CAJA[001]
~SUCURSAL[100]
etc....

With windows Notepad we see:

~PUERTO[1]box~DOCUMENTOFISCAL[]box~DOCUMENTOREFERENCIA[2147483662]box~TIPODOCUME
NTO[0]box~CAJA[001]box~SUCURSAL[100] etc...

box= is little square zero 0

The program we use to send the stored file to the fiscal printer is very fussy, 
no extra spaces, etc. With a spooler software we tried first we had to set 
utf-8 and TXT in its settings.

I know this part is not a script defect but I am at a lost as to how to force 
the file to be created per the requirements.

Obviously I lack the necessary skills to be messing with all this!!! so I will 
be very grateful if you can help here as well.

Thanks again

Its up to you how best to handle it.  I can put a feature in to auto-number 
automatically, but I want to first know exactly how you expect the files to get 
generated.  Take into consideration that I have no background information on 
what a "new transaction" is, so you might need to pass in a parameter that 
helps this happen.

> With windows Notepad we see: ~PUERTO[1]box~DOCUMENTOFISCAL[]
This is because the web browser uses "\n" instead of "\r\n".  A quick replace 
with JavaScript will fix the newline issue using ".replace(/\n/g, "\r\n")"

    document.jzebra.append(document.getElementById(id).textContent.replace(/\n/g, "\r\n"));

> box= is little square zero 0
Perhaps you can explain a little bit more on this.  If it's not a standard 
ASCII character, you can use UNICODE format instead, which a quick Google 
search should find.

> set utf-8 and TXT in its settings
I think jzebra will export to UTF8 file if you force that as a charset.  I 
haven't tested this though.  
    document.jzebra.setEncoding("UTF-8");

I'm a bit curious how this is all sending to the printer, and what type of 
printer you are using.  Perhaps you can shed some light on that as well, as you 
are the first to request files in a specific format be written to the 
filesystem.  I'm intrigued.

Hi,

I am providing you with a demo site where the process is happening. You can 
process orders on the online POS to see from A to Z there are no real 
transactions, its a demo site. You will see comments addresed to you on the 
final print page.

http://www.maxxebiz.com/fbshops/Templates/Template002b/pos_t2_blue.php

We would like the print file created 1 per POS order, hitting the print button 
again should not create a new file (reprinting it is another issue, in case of 
paper jam, out of paper, ink, etc)

The program we use to talk to the printer was created by a system integrator in 
the Dominican Republic to interface with the fiscal printers in use here that 
capture all retail sales transactions in the printers memory as well as print 
the tickets. This is for protection against tax evasion. It is in use in 
several countries around the world.

Now what this system integrator has achieved is to be certified by the DR tax 
dept, where he provides a certification to the merchant who complies with his 
process. He gave us a spec for us to use in the print file that incorporates 
the fields and values to be passed using his interface software, he takes care 
of printer drivers (black box process)

We tested the process recently and our file structure complies. Now we are 
trying using JZebra to automate our end and make it easy for the cashier.

His software monitors the folder and sends the the created sequenced file 
invoices to the printer.

I hope that explains the process better.

By the way your tip of ".replace(/\n/g, "\r\n")" was all that was required, the 
files are looking ok now.

Hopefully we can sort out the files sequencing as 1 per order, then we are good.

Once we have 1 system certified we can enter this local market and offer small 
businesses a simple POS system.

I certainly appreciate your help, I could have NEVER figured these things out.

Normand,

The only issue I see is determining what an "order" is.  How will I know when 
to repeat numbering again?  Should the file never be overwritten?  Do the files 
get deleted after they're processed and sent to the printer?

If you can illustrate how to handle this numbering in a fashion that we can 
easily control, I can have this feature added this week.

Just tell me what scenarios can happen and how you want the numbering to 
respond.  Keep in mind, you could handle this logic server-side and pass the 
numbering to the applet as well.

Also, can it skip numbers?  If your "order number" increments and would work in 
the file name, we can just use that, right? i.e. <?php echo $order_number; ?>
       Something like this?
       document.jzebra.printToFile(outputFile +  <?php echo $order_number; ?> + "." + ext);

Yes our order number would be fine, be great to do any auditing

@Normand,

Try this and see if it does what you are looking for... Note, it would try to 
overwrite the file if you print it a second time.  I can add a feature to never 
overwrite if you determine that's needed.

Good morning!

I have made the changes you suggested above, but have not succeeded in 
obtaining a file output. I might have introduced some errors.

Maybe it would be easier to use: ~DOCUMENTOREFERENCIA[%ORDER_ID%] and not have 
to extract the %ORDER_ID% from ~NCF string

I change the print directory to "mitienda" as I had "test-div" as the folder 
and that happens to be what we are printing, but that did not change anything

I see you have taken care of the visibility of the test-div, nice touch.

I hopee its just some minor thing.

Thanks for giving so much assistance.

Regards,

Normand

It says "document.getElementById(id).textContent" is null.  Is there a reason 
why you surrounded the text lines with <p><span 
style="font-size:13px;color:#000000;">...</span></p> ?

Sorry I fixed the div. Instead of creating an code based html div, I used the 
web program to create a div and it added all that unnecessary code.

However I still see no file created.

Probably more blunders on my part?

@Normand,

You should get in the habit of using a debugger in the web browser. :)  
Chrome's "inspect element" and "FireBug" are two good places to start.... :)

You have a rogue <script type="text/javascript"> tag on line 70 and I think 
that's breaking quite a bit.

Hi,

As usual you were right, I had that line there by mistake.

EVERYTHING WORKS PERFECTLY - GREAT

I am not a programmer and do not have all the required discipline and 
experience. I am a website designer with "some" ability (usually to get myself 
in trouble!!!)

I will try too learn these tools to hopefully avoid these mishaps.

But the things you have done here in the last few days are amazing. I wont be 
getting to these capabilities anytime soon.

I am hoping to firm up an order shortly for our first POS with fiscal printer. 
After that I will have to add the "open cashier drawer" command (I saw that as 
part of the functionality of JZebra) I guess I will need more info about the 
actual hardware in use)

I will keep you informed of our progress.

I'm not sure what your line of business is, but let me know if you have any 
interest in the POS system. I can share our system, you could commercialize it 
in your area maybe. Kindly advise.

Many thanks

Sincerely,

Normand
