Printing Glitch? [0.69b]

I like to print out time scans now and then and make notes on some of the transits and SA's coming up for a client.

The print looks great but I noticed there are always several lines that are missing in multiple sections of the printout.

For example, I printed a time scan from May 26, 2021, thru May 27, 2027

It does not matter if I print in portrait or landscape, there are always chunks missing.
