CHAPTER I FEATURES AND SPECIFICATIONS
1. FEATURES
This printer has the following features:
Three Functions in One Printer
This printer provides two additional functions, copying and scanning besides the printing
function. You no longer need a lot of peripherals and can save space in your office. This
is helpful especially for SOHO users.
High Resolution and Fast Printing Speed
True 600 dots per inch (dpi) with microfine toner and 10 pages per minute (ppm) printing
speed (A4 or Letter paper).
Enhanced Printing Performance and User-Friendly Operation for Windows
The dedicated printer driver and TrueType
TM
-compatible fonts for Microsoft® Windows 3.1
and Windows 95/98 are available on the floppy disk and CD-ROM supplied with your
printer. You can easily install them into your Windows system using our installer
program. The driver supports our unique compression mode to enhance printing speed
in Windows applications and allows you to set various printer settings including toner
saving mode, custom paper size, sleep mode, gray scale adjustment, resolution and so
forth. You can easily setup these print options in the graphic dialog boxes through the
Printer Setup menu within the Windows Control Panel.
Printer Status Monitor with Bi-directional Parallel Interface
The printer driver can monitor your printer’s status using bi-directional parallel
communications. A high quality bi-directional parallel printer cable to the IEEE 1284
standard is recommended.
The printer status monitor program can show the current status of your printer. When
printing, an animated dialog box appears on your computer screen to show the current
printing process. If an error occurs, a dialog box will appear to let you know what to
correct. For example: when your printer is out of paper, the dialog box will display “No
Paper” and instructions for the corrective action to take.
Versatile Paper Handling
The printer has a multi-purpose sheet feeder and a straight paper path mechanism.
Using this mechanism, you can load A4, letter, legal, B5, A5, A6, and executive sizes of
paper, and various types of media including envelopes, organizer paper, or your custom
paper size.
Easy Copier Operation
The copy function is easy to operate. All the operations and settings (scaling, mode, and
number of copy settings) can be set on the scanner control panel.
Document Management Application ‘Visioneer PaperPort
®
LE Software’ (MFC-
P2000)
Visioneer PaperPort® LE Software is a document management application which
contains a viewer, editor and filing system and various links to other applications.
Visioneer PaperPort
®
LE Software is a sophisticated application and has widespread
industry acceptance and endorsements.
I-2
Sophisticated Viewer Software ‘WordCraft Unimessage™ Viewer Software’ (HLP2000)
WordCraft Unimessage™ Viewer is a sophisticated viewer for displaying and editing
graphic files. In addition to the usual image editing functions (object drawing, annotations,
highlighting, etc.) you will also be able to use this software to view both color and
monochrome images, create cover sheets for use with HL-P2000, display thumbnails of
graphics files in any of your directories and set up a referencing system for your files
using DIR (Document Indexing Retrieval).
TWAIN Compliant Scanner Driver
The scanner driver is TWAIN compliant which is a defacto standard. You can use the
scanner from other TWAIN compliant applications as well as the PaperPort application or
Unimessage™ viewer application.
Environment-Friendly
Economy Printing Mode
This feature will cut your printing cost by saving toner. It is useful to obtain draft copies
for proof-reading. You can select from two economy modes, 25% toner saving and 50%
toner saving, through the Windows printer driver supplied with your printer.
Sleep Mode (Power Save Mode)
Sleep mode automatically reduces power consumption when the printer is not in use.
The printer consumes less than 13W when in sleep mode.
Low Running Cost
The toner cartridge is separate from the drum unit. You need to replace only the toner
cartridge after around 2,400 pages, which is cost effective and ecologically friendly.
The actual number of pages printed with each toner cartridge may vary depending on
your average type of print job.
Enhanced Memory Management
The printer provides its own data compression technology in its printer hardware and the
supplied printer driver software, which can automatically compress graphic data and font
data efficiently into the printer's memory. You can avoid memory errors and print most
full page 600 dpi graphic and text data, including large fonts, with the standard printer
memory.
Remote Printer Console Program for DOS
The utility program, Remote Printer Console (RPC), is available on the floppy disk and
CD-ROM supplied with your printer. When you operate your computer in the DOS (Disk
Operating System) environment, this program allows you to easily change the default
settings of the printer such as fonts, page setup, emulations and so on.
This program also provides a status monitor program, which is a Terminate-and-Stay
Resident (TSR) program. It can monitor the printer status while running in the
background and report the current status or errors on your computer screen.
Popular Printer Emulation Support
The printer supports the HP LaserJet IIP, Epson FX-850, and IBM Proprinter XL
emulations.
When you use DOS application software or Windows version 3.0 or earlier, you can use
any of these emulations to operate the printer in the 300 dpi resolution mode. The printer
also supports Auto-emulation switching between HP and Epson or HP and IBM. If you
want to set the emulation, you can do it using the Remote Printer Console Program.
