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”.
• 
We recommend to use a parallel cable that is 2.0 meters (6.6 feet) or less.
