## How to Prevent Reprinting Barcode Labels for Purchase Vouchers?
In this tutorial, we will learn how to use the **"Do Not Generate Purchase Voucher Print Label Multiple Time"** option in Logic ERP to prevent barcode labels from being generated repeatedly for the same Purchase Voucher.
***
### Objective of This Feature
* Prevent duplicate barcode label generation
* Restrict repeated printing of Purchase Voucher labels
* Avoid unnecessary duplicate barcode labels
* Improve barcode printing control
* Maintain accurate barcode records
***
### Access to the Barcode Label Printing Configuration
* Navigate to the **Barcode Label Printing** module.
* Open the **Configuration** window.
* Locate and enable the option labeled as:
> **"Do Not Generate Purchase Voucher Print Label Multiple Time"**
* Save the configuration changes.
***
### Generate Barcode for a Purchase Voucher
* Navigate to the Purchase Voucher barcode printing section.
* Select the required **Purchase Voucher**.
* Select the required item.
* Click on **Create**.
* The **Barcode Printing Design Selection** window will appear.
* Click **Yes** to print the barcode directly or select **No** to open the barcode design window.
* Select the required barcode design.
* Proceed with printing.
**Result**
Since the barcode label for this Purchase Voucher has not been generated previously, the system successfully generates and prints the barcode label.
***
### Attempt to Reprint the Same Barcode
* Return to the barcode label printing window.
* Select the **same Purchase Voucher** again.
* Select the required item.
* Click on **Create**.
**Result**
* The system detects that barcode labels have already been generated for the selected Purchase Voucher.
* An information message is displayed indicating that the **barcode is already generated for the selected voucher**, and the system restricts the duplicate generation.
***
### Key Benefits
* **Prevents Duplicate Labels:** Stops the same Purchase Voucher from generating barcode labels multiple times.
* **Avoids Repeated Printing:** Reduces the risk of accidentally printing duplicate labels.
* **Improves Inventory Accuracy:** Helps maintain proper barcode records.
* **Better Printing Control:** Ensures each Purchase Voucher is processed only once.
* **Reduces Operational Errors:** Minimizes duplicate barcode generation caused by repeated processing.
***
### Important Note
Once a barcode label has been generated for a Purchase Voucher, enabling this feature prevents the system from generating the barcode label again for the same voucher.
***
### Final Outcome
By enabling **"Do Not Generate Purchase Voucher Print Label Multiple Time"**, Logic ERP ensures that barcode labels for a Purchase Voucher cannot be generated repeatedly. Once the barcode has been successfully printed, any further attempt to generate the same label is restricted by the system.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/reports-queries/item-report/barcode-labels-printing/barcode-labels-printing-configuration/do-not-generate-purchase-voucher-print-label-multiple-time.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
