OK, so this documentation is in error.  Can you file a bug report on this?

    http://www.cups.org/str.php

What it *should* say is this:

    The name may contain up to 40 ASCII characters within the range of decimal 33
    to decimal 126 inclusive, except for the characters comma (44), slash (47) and
    colon (58).  The user text, if supplied, may not exceed 80 bytes in length.

You *can't* use the comma in the name because that is used by CUPS as a value delimiter. Appendix B of the PPD specification defines the standard PageSize names to use and the convention for new names and qualifiers, e.g. Letter.FullBleed would be a qualified version of Letter that has margins of 0, and cupstestppd warns when you use a non-conforming name.

Not in the programming world when defining allowable *characters*.
