Printer functions convert binary cell values into the print forms that Emacs will display on the screen.
A printer can be a format string, like ‘"$%.2f"’. The result string is right-aligned within the print cell. To get left-alignment, use parentheses: ‘("$%.2f")’. A printer can also be a one-argument function (a symbol or a lambda), whose result is a string (right-aligned) or list of one string (left-aligned). While typing in a lambda, you can use M-<TAB> to complete the names of symbols.
Each cell has a printer. If nil, the
column-printer for the cell's column is used. If that is also
nil, the default-printer for the spreadsheet is
used.

minibuffer history, which is preloaded with the set of all
printers used in this spreadsheet, plus the standard
printers.
The 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
center the result:
