I want to print multiple copies of an e-invoice that has already been generated. What is the process to do this?

To generate e invoices from the standard version of BUSY, you can follow these steps:
First, make sure the e invoice that you are printing is before 2 days from the voucher date.
Step 1: After confirming the above option, go to the Transactions menu.
Step 2: Under Transactions, find and select GST Misc. Utilities.
Step 3: Inside GST Misc. Utilities, choose E Way Bill & E Invoice Management.
Step 4: In the next menu, click on Generate Print E Invoice.
Step 5: You will see the option Generate Print E Invoice. Select this option.
Step 6: Choose E invoice to be generated automatically if that's your preference.
Step 7: In the voucher details section, pick the Voucher type.
Step 8: Specify the starting date and ending date for the vouchers you want to work with.
Step 9: Click Load List to see the vouchers within the specified date range.
Step 10: From the list of vouchers, select the one you want to print.
Step 11: Finally, click on Print E invoice to generate and print the E invoice for the selected voucher.
Step 12: Take a physical printout of the e invoice as needed.
This sequence of steps should help you generate and print e invoices for the chosen vouchers.
