Epson Stylus Color 400 Ink Jet Printer

The Stylus Color 400 is not DOS compatible. It is designed primarily for Windows, therefore will not accept printer ESC codes. This printer uses ESC/P Raster language and the LQ models use ESC/P2. The difference in the languages prevents the printers from emulating the LQ or any other models.
You can try selecting one of the following Epson LQ models in your driver selection, but the results may not be positive.
