# COMPRESSING BITMAP DATA BEFORE SENDING TO THE MACHINE

## Overview

Bitmap image data included in the print job can be compressed using the Bitmap compression function supported at the language level by Postscript and PCL6.
By compressing Bitmap image data in JPEG, RLE, or Delta Row format*1, print job data from the printer driver can be reduced to improve overall throughput.
The compression level can be set to "None", "Very High Quality", "High Quality", "Medium Quality", or "Draft".
*1 When PostScript is used, only JPEG is supported.

- This function is available in a Windows environment.
- Printer driver PCL6 or PS can use this function.
