%22 — LU1 End Bracket
If Option #54 is enabled, this PFS is sent to the printer when an End
Bracket indicator is presented by the host. The user should ordinarily define
this PFS with a printer reset command, or with an emulation switching
command for a multimode printer.
%23 — Switch to Serial Port 1 Host
When switching from any other host (or neutral) to the serial port 1
(SERIAL 1) alternate host, this PFS is sent out.
%24 — Serial Port 1 Host Finished
After all serial port 1 (SERIAL 1) alternate host data has been processed,
this PFS is sent out.
%25 — Switch to Serial Port 2 Host
When switching from any other host (or neutral) to the serial port 2
(SERIAL 2) alternate host, this PFS is sent out.
%26 — Serial Port 2 Host Finished
After all serial port 2 (SERIAL 2) alternate host data has been processed,
this PFS is sent out.
%27 — LU1 Bind
A job boundary PFS used when Option #57 is enabled. Before data may be
sent to a device like the ALLY PLUS, the host must perform a “bind” with
that device. This PFS, if it has been programmed, is sent to the printer when
that bind occurs; by default there is no data in this PFS. A typical use of this
feature is to offset printing or to reset the printer. On a Xerox 4213 (or other
multimode printer) this PFS could be used to change emulations.
%28 — LU1 Unbind
A job boundary PFS used when Option #57 is enabled. If an LU1 bind has
occurred and an LU3 bind is attempted, the ALLY PLUS will send an LU1
unbind PFS to the printer. This is another logical place to perform resetting
of the printer (or an emulation change). By default there is no data in this
PFS.
