declare printer command

["Cadenas, Maria (MT)" <MCadenas@DOW.COM>]

I have a quick question regarding printer commands.  I'm working with a
program that does not have a declare-printer command at the setup section,
rather the entire program is populated with sections like:

declare printer
        type            = HPLASERJET
        orientation     = portrait
        lines-inch      = 7
        chars-inch      = 16.6
        !top-margin      = 1

there is not end-declare at all, and they through these type of adjustments
wherever they want a change, similar to alter-printer.

the declare printer command their using works, I was just wondering why I
can't find any references to it.
