PARALLEL INTERFACE SPECIFICATIONS
✒
Note
To ensure best quality performance use an IEEE 1284 compliant parallel
cable between the printer and your computer. Only IEEE 1284 cables
support all of the advanced printing capabilities, like bi-directional
communication. These cables will be clearly marked with “IEEE-1284”.
Interface Connector
Printer Side: Amphenol FCN-685J036-L/X or equivalent
A shielded cable should be used.
