The list element can be:
string it should be an option for `ps-lpr-command' (which see).
For example: \"-o Duplex=DuplexNoTumble\"
symbol it can be a function or variable symbol. If it's a function
symbol, it should be a function with no argument. The result
of the function or the variable value should be a string or a
list of strings.
list the header should be a symbol function and the tail is the
arguments for this function. This function should return a
string or a list of strings.
Any other value is silently ignored.
It is recommended to set `ps-printer-name' (which see) instead of including an
explicit switch on this list.
See `ps-lpr-command'."
