Unsolicited Messages
You may receive unsolicited messages from your printer. Unsolicited messages use
the same syntax as status messages. These messages are transmitted sequentially
as ordinary data through the communication channel, with other characters written to
a standard output file. These messages are bracketed with
%%[
and
]%%.
%%[ Error: error type; Offending Command: operator ]%%
The interpreter has detected an
error
while executing
operator
and invoked
handleerror.
%%[ Flushing: rest of job (to EOF) is ignored ]%%
The rest of the current print job is discarded because of a previous error or other
ending, such as a stop or Ctrl-C. The printer ignores further input until it
determines the end of the print job.
%%[ exitserver: permanent state may be changed ]%%
The PostScript emulation program has exited successfully from the server
normal save or restore context; therefore, it can make permanent changes to
system parameters or virtual memory.
