2 DATA0 These signals represent information for the 1st through 8th bit of parallel
data, respectively. Each signal is HIGH when data is logical 1, and LOW
3 DATA1
when logical 0.
4 DATA2
5 DATA3
6 DATA4
7 DATA5
8 DATA6
9 DATA7
10 ACK 10µs low to acknowledge receipt of data.
11 BUSY Printer sets line low when ready to receive data.
12 PAPER High when paper runs out. .
13 SELECT High when printer is on-line.
14 - 15
16 SIGNAL GND Signal ground
17 CHASSIS Chassis ground (isolated from signal ground)
18 +5V +5V DC output from printer
19 - 30 GND Twisted pair ground return
31 RESET Printer is reset when this signal goes low.
32 ERROR Low when printing cannot continue due to error.
33 EXT GND External ground
