What problems is VueScan solving and how is that benefiting you?
I have old but good-quality scanners. One, a MicroTek i800 flatbed transparency scanner, would not work at all with any of my current Mac equipment. Neither Apple nor MicroTek offer any support for this scanner with my system.
The scanner itself is only ten years old, hardly ancient for an expensive piece of office equipment and I imagine many other scanners and printers fall into this trap of big corporations discarding customer support once it's no longer lucrative for them.
After searching for solutions, trying several suggestions, and also trying several third-party software solutions, the only fix that came through was VueScan.
And it's primarily because VueScan is from a small software developer who takes the utility and longevity of their product seriously. It's worth it to me to pay for the pro version and get my scanners back and also to support independent software developers. Review collected by and hosted on G2.com.
