This driver is for Windows 95 but should work ok in Windows 98. Here's what Citizen states
The Printiva Series has been discontinued. Currently, we have drivers for Windows 3.x and Windows 95. There will be no updates to these drivers.
Drivers for Windows 98, Window NT, and the Macintosh are not available.
There will be no future drivers developed for the Printiva Series.
We tested the the Printiva Windows 95 driver under Windows 98 and it worked well in our testing. However, we cannot guarantee that it will work
well in Windows 98 under all conditions. We recommend using the Printiva with Windows 3.x and Windows 95.
