## How to Configure Optional Lines in Document Printing (Skip Field if Blank)?
In this tutorial, we’ll demonstrate how to configure the option that **automatically skips any field if its value is blank** in both **Visual Base Printing** and **Designer Printing** formats.
***
### Enable Skip Blank Fields in Multiple Printing Configuration
* Go to Menu/Configuration and select **"Sale Multiple Printing Configuration"**.
* Select the **required series**.
* Optional lines can be defined in both the **header** and **footer**.
* Example: If a bill contains items only under a single GST slab, you can skip the other tax slab fields automatically.
* Go to the **Footer section**
* Locate the option Functions Icon (top-right).
* From the dropdown, choose **Skip if All Fields are Blank**.
* Save the configuration.
* Open the Sale Bill **Print Preview**.
* Blank fields are skipped (e.g., only GST 5% appear while other slabs are hidden).
***
### Enable Skip Blank Fields in Designer Printing
* Go to Menu/Continuous Printing and then select **"Sales Bill Print Designer and Printing"**.
* Select the **required configuration** and **sales bill**, then click **Refresh**.
* Preview the bill first to compare before/after results.
* Example: Discount or IGST may appear even when no value is defined.
* Close the preview and click **Design**.
* From the Menu Bar/Options click on **Preview Options**
* Locate the option labeled as " **Allow Optional Lines in Printing**."
* Now, go to the **Footer (Total Details section)**.
* Click between the fields → Open **Options → Skip Line if Value is Blank**.
* A caret (^) symbol will appear, marking it as optional.
* Apply this setting to all relevant fields (e.g., IGST, Discount, etc.).
* Save the layout and preview again.
* Fields with no values are now hidden automatically.
