Remarks

Device driver for Sharp JX-300, JX-450, JX-600 and Howtek ScanMaster and 
ScanMaster II color scanners using the National Instruments PC-488, PC-488A, 
and 16-bit GPIB interface. Requires correct installation and configuation of 
the device driver GPIB.COM (National Instruments Driver) using IBCONF.EXE 
(National Instruments configuration program) to configure it. Passing
