Powering Off The Printer - Digital Equipment DECwriter 110i Service Manual

The 36-pin connection cable is NOT supplied with the printer and must not be
more than 2.5 meters long. Optional parallel interface cables are however
available.
The following figure gives the connector's pin-out.
Before powering off the printer make sure the print head is at the far right-hand
side of the carriage. It should automatically reach this position after a few
seconds of printer inactivity. The purpose for this is to tightly seal the print
nozzles to prevent the ink inside them from drying-out.
NOTE: If the personal computer is powered off while the printer is still on, the
printer will automatically reset itself. If the printer is powered off during the
reset phase, the print head may stop outside its parking position.
It is therefore suggested to power off the printer before the personal computer.
