SAFETY INFORMATION
`lhis printer is a page printer which operates by means of a laser. There is no possibility of danger from the laser, provided the printer is operated accordrng to the instructions in this manual provided. Since radiation emitted by the laser is completely confined within protective housings, the laser beam cannot escape from the machine during any phase of user operation. For Europe Usem;

General Description
1.1 FEATURES
The EPSON@ EPL-9000 is a non-impact page printer that combines a semi-conductor laser with electr~photographic technology. This printer is small and light, and features high-speed, high-resolution printing. Maintenance is very easy as a result of various built-in diagnostic functions. The main features are: L1 Q c1 D c1 cl c1 c1 c) cl tl la Ct Q Q c1 D D c1 c1 No ozone Printing speed -- 8 ppm (pages per minute) (A4 or letter size) Resolution -- 600/300 dpi (dots per inch) Small footprint Easy maintenance HP@ LaserJet@ 4 emulation mode 45 built-in scalable fonts (35 Intellifonts and 10 TrueType fonts) ESC/P 2'" emulation High-performance controller (the controller's CPU is a 19.2 MHz SPARKlite (MB86930)) Bi Resolution Improvement Technology (BiRITech) r#fh& the print quality by eliminating jagged edges from images and characters on 600 dpi and 300 dpi printing. Optional EPSONScript Level 2 (PostScript@ compatible) module EPSON Micro Gray Technology (EMGTech), which is availabie when using EPSONScript Level 2 mode, refines gray scale printing to be comparable to printing on a 12~dpi printer Small and low-cost optional LocalTalkTM interface module 2 MB standard RAM and up to 64 MB RAM with the addition of optioml SIMMS Bidirectional parallel interface High-speed serial communication rate of 57.6K bps High-speed parallel communication rate of approximately 400 KB/second A multi-user, multi-emulation mode ES (Intelligent Emulation Switch) allows switching between EPSONScript mode and another mode SPL (Shared Printer Language) enables switching of the printer mode by command

Logic O is "SPACE" and logic 1 is "MARK" state must be maintained between transmitted character codes.
Handshaking
When the vacant area for data in the input buffer drops to 256 bytes, the printer outputs an X~FF cede or sets the DTR signal leveI to LOW, indicating that the printer cannot receive more data. Once the vacant area for data in the buffer recovers to 5X2 bytes, the printer outputs an X-ON code or sets the DTR flag to HIGH, indicating that the printer is again ready to receive data. .,.,: ~,,. G
Protocol
There are two types of protocols, as listed below, and each of them can be designated by SelecType independently.
s DTR/DSR protocol
SelecType is used to execute the DTR/DSR control protocol. The DTR signal is set to HIGH when the printer is ready to receive data, and to LOW when conditions indicate an error or that the receiving buffer is full. When the error is cleared and the printer returns to on-line mode, the signal returns to HIGH. When SelecType is used to set the DTR controI OFF, DTR is always set HIGH. The printer transmits TXD only when DSR is at the HIGH level (DSR is always considered HIGH when the SelecType setting for DSR is OFF). X-ON/X~FF transmission is independent of the DSR state.
s X-ON/X-OFF (DC1/DC3) protocol
SelecType is used to execute the X-ON/X-OFF protocol. The X-OFF (DC3) code is output if status indicates an error, and the printer warns the host to stop data transmission within 128 characters. No further X-OFF codes are sent in response to additional data received from the host after the X-OFF code has been sent once. The X43N (DCl) code is output after all renditions given in the error are cleared. When the remaining capacity of the receive buffer reaches 256 characters, X-OFF (DCl) is output once. It is sent only once, even if there are multiple errors. The printer goes on line automatically at power on, and outputs an X-ON code. Transmission of X~N/X-OFP codes can be defined by SelecType.

1.4.6 Emulation Mode Switch Functions
This section describes the emulation mode switch function. 1.4.6.1 Emulation Switch by SPL The two types of emulation switch functions described below are available on this printer. Together they are referred to as SPL (Shared Printer Language).
EJL: EPSON Job Language
This is EPSON's origiml language system. It is able to skip among various destinations, as shown in Figure 1-12.
PJL: Printer Job Language
This is HP's original language, which is available with the LaserJet 4 printer. It is able to skip among various destinations, as shown in Figure 1-12. The precise specifications for this language are based on the HP LaserJet 4.
The
figure below shows three types of mode switching.
Neither EJL nor PJL switches the mode directly. They first exit the current mode and return to EJL or PJL. Then they enter another mode.

1.4.7 Bi Resolution Improvement Technology
The EPL-9000 printers have BiRITech (Bi Resolution Improvement Technology), which is designed to improve print quality at 600 dpi and 300 dpi. By this method, the dot map data extracted from the image data is reassembled to improve print data. The main improvement of this technique is m eli minating "jjggies" in diagonal lines. It is most effective when the dot map data fits the development characteristics of the printer mechanism well. It is therefore necessary to set appropriate values in SelecType.

(When 600 DPI printing)
Figure 1-14. Effect of BiRITech
BiRITech is not as effective for printing a mesh pattern or gray scale. In such cases, BilUTech must be set to OFF. ('The default setting is MEDIUM.) Since the J3iRlTech effect
depends on the toner condition, it should be adjusted when the imaging cartridge is replaced or after the imaging cartridge is used for a long time.
The following settings are available in SelecType Level for RITech: DARK, MEDIUM, LIGHT, OFF. When the toner density of area A is almost the same as that of area B (as shown m the figure below), the RITech setting is at its optimum setting. In other words, the optimum setting is achieved when it is difficult to distinguish the shape of area A from that of B.
