Putting the printer online or offline

You can send <XOFD and <XON> control codes (described in Chapter 2

you are using a parallel interface, any data your computer sends after you put

To put the printer back online, either press ONLINE on the front panel or

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.
