This page describes optimal settings for Okidata 320/420 and 321/421 Turbo printers (click here for non-turbo printers). The Lot Wizard dealer software can use virtually any dot-matrix printer to print state forms, bank contracts, odometer disclosures, insurance agreements, buyers guides, and other multi-part or carbon copy car deal forms. We recommend the Okidata printers only because we have used them exclusively in our office for years.
The drivers we recommend all come with Windows and require no discs or downloads. Please try the drivers in the order they are listed below.
The use of Epson drivers requires the printer Emulation Mode to be set to Epson FX, contrary to what is recommended below.
There are three settings that you will need to make sure you have set correctly for optimal use with our Lot Wizard software; Printer Emulation, Bottom Margin and Paper Out Override.
Watch our videos that demonstrate how to print out a list of your Okidata's settings and how to change the Okidata settings.
Important settings:

You use the front panel keys to change the defaults for the printer parameters. The changes you make in the Menu Mode are automatically saved when you exit the Menu Mode and are retained, even when you turn the printer off.
