Hello everyone,
I’m working on an implementation where I need to generate barcodes for each item in the Item Doctype. In the Inventory section of the Item form, there is a Barcode child table with fields like Barcode and Barcode Type, but I’m not sure how to use it or where this barcode is used within the system.
My questions are:
- How can I automatically generate barcodes for each item in the Item Doctype?
- Is there a recommended format or barcode standard that should be used (e.g., Code128, QR Code)?
- Once generated, where are these barcodes used – in printing labels, invoices, or elsewhere?
- Can this be automated when an item is created or updated?
- Are there any best practices or existing plugins/apps that support barcode generation in ERPNext/Frappe?
Any guidance or examples would be highly appreciated!
Thank you in advance.
Hi,
I guess it depends on your use-case. Generally speaking, barcodes can be generated for multiple purposes, the most common being a standardize way to recognize and sell widely available/fast moving products.
For that purpose, there are entities that regulate the creation of barcodes and you have to go through them to issue new ones. example GS1: GS1 | The Global Language of Business
For internal uses, such as report tracking, manufacturing, etc. you can create them youself and assign them to anything you want. The way to do that is by adding a barcode field-type to your document. You then can either map it to another field (i.e. item_code, lot number, etc.), create an “eval:” formula Creating Custom Link Field, or a custom script to create the barcode based on your specifications.
Once you have added your barcode to the desired doctype, you can add it to a print format as usual. Once again, your milage may vary depending on your use-case. printing barcodes may be difficult depending on the type of printer you are using, I’ve had some trouble with the barcode being too long and some lines merging together when printing.
