Thank you all for taking the time to respond! I'm passing on the laptop specs to our central library IT group to help them focus on an appropriate laptop.
We will not allow direct connects to the printer, instead requiring a flash card type method for loading the designs.
We at our library will be installing the design/slicer SW, so the above recommendations will be of great help!
Once we have the portable unit put together I'll post what we chose and how it's working out.
Thanks again!
