# General Settings

The following settings are available in the **General Settings** module to allow customization of application behavior.

* **Border CSS**: Customize the border displayed around your barcode label when the **Show border** option is selected on your **Barcode Generator** record
* **Cache barcodes**: Enable/disable the caching of barcode labels. ***Note**: The app automatically manages the cache to ensure that your barcode labels are always up-to-date with the correct underlying information. It is recommended to leave this setting enabled for optimal performance.*
* **Advanced Options**
  * **Pixels per inch**: The number of pixels-per-inch to assume when calculating barcode size
  * **Redraw threshold**: Pixel difference between actual & desired size that will trigger a redraw of the barcode
  * **Redraw multiplier**: Multiplier used when redrawing a barcode for optimal sizing
