USB Interface (for Windows
98 / 2000/XP, iMac and Power Macintosh)
The printer can be connected using the Universal Serial Bus (USB) interface to a PC or Mac
which has a USB interface. Drivers that allow you to use the USB port are provided on the
CD-ROM supplied with the printer.
Popular Printer Emulation Support
These printers support the following printer emulation modes;
HP LaserJet (PCL6), PostScript
Level 3 language emulation (Brother BR-Script Level 3),
Epson FX-850 and IBM Proprinter XL.
When you use DOS application software or Windows
version 3.0 or earlier, you can use any
of these emulations to operate the HL-1850/1870N printers. The printers also support auto-
emulation switching between HP, Brother BR-Script 3 and Epson or HP, BR-Script 3 and IBM.
If you want to set the printer emulation, you can do it using the Remote Printer Console
Program.
High Resolution Control & Advanced Photoscale Technology
High Resolution Control (HRC) technology provides clear and crisp printouts. Use this function
to get smooth text print quality.
Advanced Photoscale Technology (APT) enables the printer to print graphics in 256
grayscales, producing nearly photographic quality. Use this function when you want to print
photographic images.
Environment-Friendly
<Economy Printing Mode>
This feature will cut your printing cost by saving toner. It is useful for obtaining draft copies for
proof-reading. You can select the 50% toner saving economy mode 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 for a
certain period of time. The printer consumes less than 12W when in sleep mode.
<Low Running Cost>
Since the toner cartridge is separate from the drum unit, you need to replace only the toner
cartridge after printing around 6,500 pages at 5% coverage for A4 paper for the standard
cartridge, which is both cost effective and ecologically friendly.
