I usually "select" the table with my mouse, then copy it to an MS Word document.
Usually it would paste itself as a "table". I haven't tried recently on a Plant List, but it worked with most (all?) of the seed swap artifacts.
Then I could easily delete the parts I did NOT want, and print the rest. I work with MS Word tables a lot, to print double-sided labels. They have a nice laser printer at work, that will print double-sided, with registration/alignment of front and back usually better than 1 mm.
>> What I would really like is to print just the 'Plant' column so that I can import it into my label file to print new labels.
In your case, after copy-pasting into the editor of your choice, you could probably select just the "name" column, copy just that column, and paste just that column.
