CONTROLLING THE PRINTER Putting the printer online or offline
L You can send <XOFD and <XON> control codes (described in Chapter 2
under “Serial Interface”) to put your printer offline and then online again. If
L . you are using a parallel interface, any data your computer sends after you put
the printer offline will not be printed.
To put the printer offline send this control code:
L <xoFF> (sometimes shown as <DC3>)
To put the printer back online, either press ONLINE on the front panel or
send this command:
<XON> (sometimes shown as <DCl>)
If the printer is already online when you send the <XON> command, the
printer will cancel any incomplete line of print.

The EX-800 emulation reset command returns the printer to its default initial
parameters. When you send this command at the end of a print job the printer
will reset its parameters only after previous commands have finished. You
should, however, take the precaution of putting a form feed before the reset,
to make sure you lose no print data.
