3 Operation
The Printserver is designed to be operated via the line (host connection). The standard control panel
is fully operational, but some limitations apply to the control of the printer settings by use of the panel.
As the Printserver interface is not controlled by the panel, all commands are received from the host
system via the line. The commands are sent using escape sequences. The structure of these
commands and their effect on the printer are described in the following sections. However, changes in
paper size and CPI and LPI made in the printer front panel will also apply to the Printserver.
The control of the printer also includes testing the printer. However, the TEST key found on the panel
may also be used for the certain test procedure.
