Hi MountainMan41,
Thanks for posting your question here.
I initially expected that you would be able to work around this issue by using the "Print" option that eBay provides for each listing (over to the right of the "Description" and "Shipping and payments" tabs) as opposed to the option on your browser. However, upon testing this out, I also found that the width of the listing was not compressed to properly fit on one page horizontally.
Unfortunately, I cannot offer you a definitive solution to this issue but, if you have not done so already, you may want to contact eBay's Customer Support team to see if they have any ideas on this topic.
