Overview

This chapter describes the features, general specifications, and
dimensions of the DPP-25 and DPP-45 Series printers.

The DPP-25 and DPP-45 Series printers provide the following standard
features:

● 5 VDC input power operation.

● 6912 Character input buffer.

● Paper feed/reset/self-test input.

● Normal or inverted print.

● Underlined text.

● Double-wide, double-high, or double-wide AND double-high

characters. You can mix normal and double-wide characters on any
line.

● Bit image graphics mode using the EPSON line printer, ESC K

protocol.

● Fast paper feed through the Paper Feed switch or through the

"immediate feed command" (ESC J +n).

● Serial RS-232 interface, available on the DPP-25xxS and DPP-45xxS

printers.

Features 1-1

● Centronics interface, available on the DPP-25xxC and DPP-45xxC

printers.

● Parallel interface, available on the DPP-25xxP and DPP-45xxP

printers.

The following features are optional:

● 12 VDC power input (includes a linear regulator), available on the

DPP-2512x and DPP-4512x printers.

● 120 VAC power input (includes the linear regulator and a 14 VAC,

20 VA wall mount transformer), available on the DPP-25ACx and
DPP-AC12x printers.

The interface type and the power input used are indicated in the model
number for the printer, as shown in Figure 1-1.

For example, a DPP-25 Series printer with the 12 VDC power input and
the RS-232 serial interface is model number DPP-2512S. A DPP-45
Series printer with the 5 VDC power input and the parallel interface is
model number DPP-4505P.
