CHAPTER I

PRODUCT OUTLINE

CHAPTER I PRODUCT OUTLINE

1.FEATURES

This printer has the following features:

2400 dpi Class Resolution

The printer prints at a default resolution of 600 dots per inch (dpi). You can get a higher print quality, equivalent to 2400 dpi class resolution by using Brother technologies: High Resolution Control (HRC) and Color Advanced Photoscale Technology (CAPT).

High Speed Color Laser Printing

You can print crisp images in brilliant 24-bit color.

This printer can print at speeds up to 31 pages per minute in monochrome mode and 8 pages per minute in full color mode. The HL-2700CN controller uses a high speed 64-bit RISC microprocessor and special hardware chips, to ensure fast print job processing.

High Resolution Control (HRC)

The high resolution control (HRC) technology gives you clear and crisp printouts and improves even the 600 dpi resolution. HRC is most effective when printing text data.

Color Advanced Photoscale Technology (CAPT)

This printer can print graphics in 256 shades for each color in PCL6 emulation and BR-Script3, producing nearly photographic quality. CAPT is most effective when printing photographic images.

Maintenance-Free Toner Cartridge

This printer uses four easy-to-replace toner cartridges. The toner cartridges can print up to 6,600 (Cyan, Magenta and Yellow) and 10,000 (Black) single-sided pages at approximately 5% coverage.

Universal Paper Tray

This printer loads paper automatically from the paper tray. Since the paper tray is a universal type, a number of different paper sizes (one paper size at a time) can be used. Even envelopes can be loaded from the paper tray.

I-1

Three Interfaces

This printer has a high speed, bi-directional parallel interface, USB and Ethernet 10/100BaseTX.

If your application software supports the bi-directional parallel interface, you can monitor the printer status. It is fully compatible with the industry-standard bi-directional parallel interface.

HL-2700CN can use the TCP/IP, IPS/SPX, Apple Talk, DLC/LLC, Banyan VINES, DEC LAT and NetBEUI environments. Also, many useful utilities, such as BRAdminProfessional for the administrator and Brother network printing software, are included in the CD-ROM supplied with the HL-2700CN printer.

Automatic Interface Selection

The printer can automatically select the bi-directional parallel, USB, NETWORK depending on the interface port through which it receives data. With this feature, the printer can be connected to more than one computer.

Five Emulation Modes

The printer can emulate Hewlett-Packard Color PCL® 5C (PCL6® in monochrome mode) and PostScript® 3 language emulation (Brother BR-Script 3) printers, the industry-standard HP-GL™ plotter as well as EPSON® FX-850™, and IBM® Proprinter XL® printers (in monochrome mode). You can print with all application programs that support one of these printers.

Automatic Emulation Selection

The printer can automatically select the printer emulation mode, depending on the print commands it receives from the computer software. With this feature, many users can share the printer on a network.

Data Compression Technology

The printer can internally compress the received graphics and font data in its memory so it can print larger graphics and more fonts without additional memory.

I-2

Various Fonts

The printer has 66 scalable and 12 bitmapped fonts. The fonts that can be used will vary according to the selected emulation mode.

In PCL mode, you can also print the 13 kinds of bar codes listed below. In BR-Script mode, the printer has 35 scalable fonts.

< Bar Code Printing >

This printer can print the following 13 types of bar codes:

•	Code 39	•	UPC-E
•	Interleaved 2 of 5	•	Codabar
•	EAN-8	•	FIM (US-PostNet)
•	EAN-13	•	Post Net (US-PostNet)
•	EAN-128	•	ISBN (EAN)
•	Code 128	•	ISBN (UPC-E)
•	UPC-A

Panel Lock Setting

If the panel button settings have been changed, the printer may not work as expected. If you are an administrator of this printer, you can lock the settings to prevent changes from being made.

Power Save Mode

The printer has a power saving mode. Since laser printers consume power to keep the fixing assembly at a high temperature, this feature can save electricity when the printer is ON but not being used. The factory setting of the Power Save mode is ON so that it complies with the EPA Energy Star new specification.

Toner Save Mode

The printer has an economical toner save mode. By using this feature you can substantially reduce operating costs and extend the life expectancy of the toner cartridges.

Reprint Setting

The printer saves data that you reprinted. You can reprint a document without sending the data again from your PC. If you do not install a CompactFlash™ card, you can reprint from RAM.

Network

Ethernet 10/100BASE-TX enables you to use the printer in the following environments:

(TCP/IP, IPX/PSX, Apple Talk, DLC/LLC, NetBEUI)
