In the past I've had problems with gridlines on tables not printing the same as on screen. However, today, no matter what grid settings I use or table style I select, no grid lines will print. Background colors will print though.
Yes! Just discovered it today. Same issue, gridlines no longer printing in Edge or Chrome.
If it helps, they still print in Internet Explorer. Mine has a light colored border artifact, and was shrinking the image no matter what settings I used. Zooming in to 120% gave a workable band-aid for me. (Internet Explorer, print preferences, Detailed Settings tab, Basic section.)
I did try printing from IE and get the same issue - I tried printing to PDF (using two different options - PDF995 and AdobePDF), MS XPS, an actual printer, and even sending to onenote. All gave the same result without gridlines.
