Parallel Port Optimizer
Using the Parallel Port Optimizer

Iomega ToolsNT includes a Parallel Port optimizer that can automatically configure your Iomega software to use the fastest transfer mode for your Zip or Jaz drive. To use the Optimizer tool, double click on the "Parallel Port Optimizer" icon in your Iomega ToolsNT Windows group.

The parallel port model of the Zip drive and Jaz Traveller support three modes of data transfer, which have different transfer speeds.  When installed, the Zip Parallel Port/Jaz Traveller driver uses the most compatible, but slowest, transfer mode to ensure the broadest base of compatibility. If your computer has a bi-directional parallel port, the driver can be set to use a mode which provides higher data transfer speeds.

The fastest mode supported by the parallel port Zip drive and Jaz Traveller requires a special "Enhanced Parallel Port" (EPP) chip set to be present on the host computer. Because of the variety of EPP chip sets, and because there are some chip sets that mimic a true EPP chip but do not support EPP transfers, not all systems with "EPP" can support this mode for your Zip drive or Jaz Traveller.
