SunVTS 3.0 Test Reference Manual

Printer Test Hardware and Software Requirements

The ecpp(7) driver is installed with the OS if the system being tested supports the ecpp(7) device. To run the optional printer subtest, a Centronics or ECP-mode printer must be attached to the printer port. To run the optional external loopback test, a passive loopback connector must be installed on the printer port.

Note -

The external loopback test is intended for Sun internal manufacturing use only. It requires a custom loopback connector not available to an external customer.
