Lexmark C762 User Manual

Table 8-1 shows all protocol timings in nanoseconds.

Your printer is equipped with 

 protocol, which is an enhanced parallel 

interface protocol. Fastbytes protocol may give you a faster data transfer time on some 
personal computers and operating systems. Fastbytes protocol is the printer default.

If you have data transmission problems between your personal computer and the 
printer, change the parallel protocol to 

. This causes the printer to operate in 

IEEE-compliant compatibility mode.

The following illustration shows the typical timing sequence.
