Notes for Developers
Please note that the driver files in this evaluation kit are for evaluation purposes only. Developers can obtain free
drivers suitable for distribution from the web site at www.in-system.com. Selecting “Drivers”, filling out the informa-
tion in the “Build Me One” section and then selecting the “Submit” button will generate a request for drivers to In-
System Design. Select “Frequently Asked Questions” to obtain more details about the required fields such as
Vendor ID. If the information is entered correctly, a response will be sent for verification within 2—5 working days.
Use of the USS-720 Evaluation Kit by developers implies a basic understanding of the USB and IEEE 1284 inter-
faces as well as basic competency in board design and Windows driver programming. The information provided in
this kit is intended only as a guide for the development of a USB-to- IEEE 1284 bridging solution and, as such, is
not warranted for suitability to any particular purpose.
Following are additional notes regarding the software provided with the USS-720 Evaluation Kit:
USB Driver and Port Monitor
The USS-720 is supplied with a USB driver and a USB port monitor. The port monitor allows Windows printer
drivers to print to an IEEE 1284-compliant printer connected to the USS-720. Note that the supplied software will
work only with printer drivers that use the Windows spooling system to interface with the USS-720 USB port
monitor. See the USS-720 USB Port Monitor Application Note in this Manual for details.
Plug and Play
The Plug and Play capabilities of the supplied software are limited to the enumeration of the USS-720 device only.
Port Creation
The USS-720 software driver supports printing via the creation of a port named USBLPTx, where x is an integer
between 1 and 127. Each instantiation of the driver will generate another USBLPTx port. If two developers both
have products based on the USS-720 connecting to the same USB bus, it may not be clear which device is
connected to which USBLPTx port.
