When you want to change a persistent parameter, begin the file with
this exitserver command:
serverdict begin Ø exitserver
The serverdict is another special dictionary containing definitions
controlling the printer. The above command works where 0 is the
system administrator password. If the password is incorrect,
exitserver executes the error, PasswordIncorrect (which
immediately invokes stop, bypassing errordict). If the password
is correct exitserver responds with the message
%% [exitserver: permanent state may be changed]%%
as a positive acknowledgment to the exitserver request.
The PostScript program executed between a successful exitserver
and the next end-of-file is permitted to invoke the statusdict
operators that may change persistent parameters. Additionally, all
changes made to the state of the PostScript virtual memory (VM),
such as creating new objects and storing values into dictionaries,
persist until power-off. The modified virtual memory appears as
the initial state of all subsequent jobs.
During execution of this program, the VM is not protected from
harmful changes that could cause printer malfunction. (This
permits the printer’s software itself to be patched, should that
become necessary.) Also, VM resources consumed by that program
remain in use indefinitely. The only way to reclaim them is to turn
the printer off and on.
