EPP Register Addresses, continued
Notes:
1. These registers are available in all modes.
2. These registers are available only in EPP mode.
Each register (or pair of registers, in some cases) is discussed below.
11.2.1
The CPU reads the contents of the printer's data latch by reading the data port.
11.2.2
The CPU reads the printer status by reading the printer status buffer. The bit definitions are as follows:
DEFAULT
EPP Address Port (R/W)
Control Swapper (Read)
EPP Data Port 0 (R/W)
EPP Data Port 1 (R/W)
EPP Data Port 2 (R/W)
EPP Data Port 3 (R/W)
