Data transfer must be carried out by observing the ACKNLG or

BUSY signal. (Data transfer to this printer can be carried out only

after receipt of the ACKNLG signal or when the level of the BUSY

signal is LOW.)

5.

Under normal conditions, printer cable pins

11, 12,

and

32

are acti-

vated when the paper-out condition is detected. The ESCape”8”

code disables pins 11 and

32,

but not pin

12.

Those computers that

monitor pin

halt printing when the paper is out, making ESCape

“8”

ineffective.
