The ECP/EPP/SPP or Bi-directional refers to the BIOS settings. Windows
generally reads this, then sets itself to the appropriate mode. A dot
matrix printer can be painfully slow, unless it's built in fonts (if it has
any) are used.
Most dot matrix printers (Usually older models) are happy with SPP or
hopefully ECP.
Bi directional can be a variation on SPP, or in addition to it.
This whole thing gets deeper than I want to go, except to say that things
have actually gotten simpler.
