As the code in my previous post has all the necessary variables and functionality, you can now engage anyone in the Job Board to do it for you specific to your printer.

If you print all your barcodes in one A4 page then you can use a regular printer with Avery like labels - but printing on them may waste paper if you just need one or two.

@joe: Move the defines to sys_prefs table with appropriate settables in the Company Setup and incorporate it into the core if found useful.

Additional variables could be number of barcodes per sheet (here 1) besides suppressing the header if not necessary.

$barcode = str_pad($trans['stock_id'], 7, '0', STR_PAD_LEFT);
$barcode = substr($barcode, 0, 8); // EAN 8 Check digit is auto computed and barcode printed
$rep->write1DBarcode($barcode, 'EAN8', $rep->cols[$firstcol++], $bar_y + 22, 22, $SysPrefs->pic_height, 1.2, $style, 'N');

The default FA reporting/includes/barcodes.php file is from the TCPDF 's 1dBarcode library when used.

The reporting/rep303.php file however uses another library's extracted barcode functionality which supports only the following subset of formats:

EAN, EAN-8, EAN-13, GTIN-8, GTIN-12, GTIN-14, UPC, UPC-12 coupon code, JAN

Using another subset of TCPDF from a GitHub project for barcode generation is also feasible. This library is set to be PHP 5.4+ compatible but for backwards compatibility with PHP 5.3.x, just replace all instances of "= []" with "= Array()" in it's src/BarcodeGenerator.php file.

Sample code for using it in a standalone manner would be:

<?php
include('src/BarcodeGenerator.php');
include('src/BarcodeGeneratorPNG.php');

$generator = new Picqer\Barcode\BarcodeGeneratorPNG();
file_put_contents('src/files/081231723897-code128.png', $generator->getBarcode('081231723897', $generator::TYPE_CODE_128));
echo '<img src="data:image/png;base64,' . base64_encode($generator->getBarcode('081231723897', $generator::TYPE_CODE_128)) . '">';

The above will both generate a file and display it inline as well.

Items and Inventory => Items => Add New Item
You will now see the EAN-8 Barcode which if clicked, will yield a random EAN-8 barcode

Any other barcodes you will need to make changes in the codebase and you can also use third party online tools to generate them like:

https://barcode.tec-it.com/en/EAN8
https://www.free-barcode-generator.net/code-128/

Items and Inventory => Inventory Reports => Stock Check Sheets => Select "Yes" for "Show Pictures" and optionally "Inventory Column" and now all barcodes will be listed.

Since you want code-128 barcode and one barcode per sheet with your fields listed there, just edit the Stock Check Sheets reporting/rep303.php file to suit your need.

If you need technical assistance for it, post your specs and bounty in the Jobs board and hopefully someone will assist you.

barcode number
name item
price ( got list price from type sales for example if i need print barcode by list retail price is retail - if need wholesale print wholesale  )

and i need one item in one page by ( size 2.5 cm width × 5 cm height ) to print one item in one page
for example 20 item = 20 page by this size

thanks
