PHP class to generate barcode in Code39 standard with height and width adjustment

Asked

I’m having difficulty generating barcodes in PHP, by default code39, containing 10 digits (numbers only), for printing the web page containing the barcode in thermal printers.

I have tested several classes, but have error in optical reading.

Could someone indicate a good PHP class to generate barcode in the default code39 and allowing the height and width of the barcode to be adjusted?

Preferably, something that can be used as follows:

<img src="/barcode.php?code=' . $cod_barras . '&largura=180&altura=80" />

Important: I need it to work without any dependency other than PHP and the library GD.

Thanks in advance for any help!

    I usually use one, but it’s for Laravel 4 and 5. It’s called Milon Barcode.

  • Thanks for your attention, but I need it to work without any dependency beyond the GD library.

  • Can you install where? I use packagist. There you find anything for php

    Buddy, look at this https://github.com/picqer/php-barcode-generator

  • Wallace Maxters: php-Barcode-Enerator got wider than the coil of the thermal printer... so when it resizes to smaller width it gets poor quality.

  • No way to configure lib resolution?

  • I lowered the resolution to 1px. In the inkjet printer is good, but in the thermal (Elgin i9) the lines come out a little "dotted". Trying several times the reader can even read, but it is not the ideal.

After trying several classes, I found one that met well with barcode printing, with 10 digits, in the Code39 standard, in thermal printers, without giving reading problems or something similar.

Despite being a class whose last update was on 09/08/2005, it worked very well for me.

I hope it helps if someone goes through the same situation I went through.
