Advanced PDF/HTML packing slip form, created and set as preferred, but cannot find to select on the "Print Checks and Forms", not sure what am I missing

1. @Panda143 Go to Transactions > Management > Print Checks and Forms. 2. Click the name of the transaction you want to print. 3. Check the box beside each transaction you want to print, or click Mark All to select and print all transactions in the list.
