there are different driver/plugin packages for scanners in repo but it will be like throwing darts since I never heard of that brand.
you do need a driver/plugin.
what does plustek offer for linux support at their website I wonder?
lots of posts around here lately about driverless printing. maybe thats an option?
--just went to there website. they dont even have Mac support! Win only. But they sell a Linux scanner (model 3140) so mixed messages there. I think you have to play around.
"plustek scanner linux" has some interesting search results
