Thanks for your question!
To confirm, you’re having issues with the font size in the Orders section? Or is this on packing slips? It could be that your browser is set to be zoomed out significantly which would impact your ability to see the orders correctly. It could also have to do with your screen resolution making things smaller.
If it is on the packing slips though I can definitely pass along the suggestion! In the meantime you can often zoom in using the Scale option before printing which should fix the issue.
If you’re still experiencing issues with the font size and it isn’t what I said above I recommend reaching out to support so you can have them log your suggestion for our developers to look into!
