existing = frappe.db.sql_list("select barcode from tabItem")
self.barcode = random.choice([item for item in map(str, range(1000,10000)) if item not in existing])

New Print Format HTML:
<table class="custom">
<tr>
<td class="papa">
<p class="text-center" style="font-weight:…
You can also consider contributing a barcode print generator to Frappe/ERPNext , it’s open source
