Notes on use
Time required until printing starts
If the host computer and the printer are not connected on a continuous basis but rather
connected every time the printer starts printing, some time may be needed for the printer to
actually start printing after the host computer commands printing. This pause is the time
required for processing the connecti
on between the host computer and t he printer, an d it
depends on the conditions of the environment where used.
In Italy, if used outside of own premises, general authorization is required.
