Launch tool # 990 "Work with AP Vendors" to print out envelopes addressed to your vendors, either one at a time or in a batch of consecutive vendor #s. Once in the tool you can page down until you find the last vendor number you have on record (jot this vendor # down). Then, highlight and use the select key to go into any vendor record. Here, you can use option F23-Print Envelope. This will take you to the Print AP Vendor Name / Address on Envelope screen, where you can enter a vendor # range for envelopes you want to print.
