Does DECprint (DCPS) work with the LRA0 parallel port?
No. The parallel printing port LRA0: found on many OpenVMS Alpha systems is capable of some bidirectional communications, with enough for basic operations with most parallel printers. DECprint (DCPS) requires more than just the simple handshaking provided by the LRA0: port, therefore DCPS does not work with the LRA0: port.
