4. 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 12 halt printing when the paper is out, making ESCape
“8” ineffective.

Printing enabled/disabled signals and control conditions
Table E-2 shows the relationship between printing being enabled or
disabled, and the on-line/off-line condition, the printer select signal
(SLCT IN), and the receipt of data on/off control character,
DC1/DC3.
