well, it's INK so I don't expect you will have any luck short of sanding and refinishing it
unless you want to bleach it.
That is, alas, what i thought, but I was living in the probably vain hope that some
Einstein of the Printing Ink World would come up with a simple solution!
I may just somehow "mop up" what I can and then place something over the top to hide the stains - most of which will be under the printer when I set it back up.
It will then be up to my Heirs and Executors to sort it out when I have snuffed it and shuffled off this mortal coil!
