Printing multiple copies without using "separate print jobs" option?

I have Writer set to collate but when I print 20 copies of a page, the window that says “Printing page 1 of 7”, “Printing page 2 of 7” etc comes up 20 times instead of sending the entire job to the printer and the printer making 20 copies. This only has occurred in the latest version. Any suggestions?

My system:
Version: 6.2.2.2 (x64)
Build ID: 2b840030fec2aae0fd2658d8d4f9548af4e3518d
CPU threads: 4; OS: Windows 10.0; UI render: default; VCL: win;
Locale: en-CA (en_CA); UI-Language: en-GB
Calc: threaded

Same with me: Version 6.2.4.2, OS: Ubuntu.

That’s not the case with me. It will display “Page 1 of 1”, no matter which page I choose for the printout.

With me Windows 10, Version 1809, 64-Bit | LibreOffice, Version: 6.2.2.2 (x64).
