Standard printer functions
Except for ses-prin1, the other standard printers are suitable only for cells, not columns or default, because they format the value using the column-printer (or default-printer if nil) and then post-process the result, eg. center it:
ses-center
Just centering.
ses-center-span
Centering with spill-over to following blank cells.
ses-dashfill
Centering using dashes (‘-’) instead of spaces.
ses-dashfill-span
Centering with dashes and spill-over.
ses-tildefill-span
Centering with tildes (‘~’) and spill-over.
ses-prin1
This is the fallback printer, used when calling the configured printer throws some error.
