Pros: Does what it's supposed to do ...

Cons: SYBA tech support is out to lunch on this issue ...

Overall Review: For Vista machines, you must first download and install the MCS7715 "USB Compound Device" driver from www.moschip.com/html/download_drivers.html During the install, Vista will twice prompt the familiar "This device driver is not Windows Vista certified" (by Microsoft) alert; go ahead and complete its installation. Next, attach the SYBA USB to Printer Port Adapter cable to your printer, turn the printer ON, and plug the USB cable into your machine. Vista should recognize your Printer and complete its installation to a "Virtual USB Port"... hope this helps.
