At a quick glance, the Postscript file generated by Okular looks OK to me (file
'debian_11-beta-20200609/var/spool/cups/d00018-001_-_print-area' in the
attached tar file); if you open that in Okular, it looks the same as the PDF
file 'numeric_test.pdf'.

The processing to fit that to the page etc. is done by CUPS (and the
corresponding so-called CUPS filters), according to the options Okular passes,
which are those for the first case (from the error_log file):

> D [09/Jun/2020:21:25:03 +0200] [Job 18] argv[5]="Collate ColorModel=KGray finishings=3 fit-to-page job-billing media=A4 number-up=1 number-up-layout=lrtb outputorder=normal page-bottom=41 page-left=10 page-right=10 page-top=10 portrait sides=one-sided job-uuid=urn:uuid:c 7d3001b-0e41-33d2-5eec-70168aa8d6ee job-originating-host-name=localhost date-time-at-creation= date-time-at-processing= time-at-creation=1591730703 time-at-processing=1591730703 document-name-supplied=okular_ufzIXL.ps PageSize=A4"

This looks OK to me at a quick glance. Therefore, this might be an issue
outside of Okular.

Some questions:

1) What happens if you print that file using the same options using command
line, i.e.:

lp -d HP_DeskJet_1000_at_fbox_hpcups -o "Collate ColorModel=KGray finishings=3
fit-to-page job-billing media=A4 number-up=1 number-up-layout=lrtb
outputorder=normal page-bottom=41 page-left=10 page-right=10 page-top=10
portrait sides=one-sided job-uuid=urn:uuid:c
7d3001b-0e41-33d2-5eec-70168aa8d6ee job-originating-host-name=localhost
date-time-at-creation= date-time-at-processing= time-at-creation=1591730703
time-at-processing=1591730703 document-name-supplied=okular_ufzIXL.ps
PageSize=A4" debian_11-beta-20200609/var/spool/cups/d00018-001_-_print-area

2) Does it make any difference if you just use this command?

lp -d HP_DeskJet_1000_at_fbox_hpcups -o fit-to-page
debian_11-beta-20200609/var/spool/cups/d00018-001_-_print-area

3) What happens if you print the PDF file numeric_test.pdf_able-job_1474.pdf
from Okular to the CUPS-PDF printer instead of your physical one? (seems to
work fine for me on Debian testing)

4) Do you have any other printer you can test with, and if so, how does it
behave?
