2 / 4 Computer Adapter
If another print job is started parallel to a running print job on
the second connected computer, a Windows-generated error
message is generally displayed immediately to indicate that the
connected printer is not available. The driver attempts to
establish contact with the printer without delay but of course
fails, since the printer is at this moment already used by
another computer. If the driver wait time until an error message
is generated cannot be set, the user must wait to start the print
job until the previous job has finished. If both problems cannot
be resolved by configuring the printer driver, you can generally
solve the problem by installing an equivalent, non-bi-directional
standard printer driver.
Supply voltage
The Adapter is designed using power-saving CMOS technology
and can generally be powered with no problem by the signal
lines of the parallel interface..
Optionally it is possible to power the Adapter via an external
power supply having an output voltage or 5V regulated. Such a
power supply can be ordered from W&T under Part no. 11050.
