STROBE– Computer Must pulse low for at least 0.5 micro-
second to clock data on DB1-DB8 lines;
data must be present for at least 0.5
microsecond before and after pulse
)Note: The STROBE parameter on the
Setup menu lets you control whether the
printer captures the data byte on the
leading or trailing edge of STROBE–.
