Some Brother printers are supplied with two printer drivers: a PCL driver and a BR-Script (PostScript language emulation) driver.
For Windows® Users:
Generally speaking, we recommend you use the PCL driver. This is the default driver for Windows® PCs. However, you may want to use the BR-Script driver if you are using a DTP (Desk Top Publishing) application such as Quark Express or Adobe Illustrator.
For Macintosh® Users:
Generally speaking, we recommend you use the Brother Laser (PCL) driver. This is the default driver for Macintosh®. However, you may want to use the BR-Script driver if you are using a DTP (Desk Top Publishing) application such as Quark Express or Adobe Illustrator.
