HP L5 manual Printer-Specific Differences

Updated Features Printers with a “B” or “C” revision code, indicated by the third digit in the serial number, have the following additional new features. (Print the self-test to see the serial number.)

Two-Byte Fonts. Provides support for two-byte (large) fonts with more than 256 characters. Two-byte fonts support such large symbol set mappings as Unicode, Shift-JIS, JIS208, and Big5. Two-byte fonts are compatible with current PCL data structures.

Frame Buffer/MEt Architecture. Provides MEt (Memory Enhancement technology), which overcomes memory contention problems. Drivers can use the PJL SET command (@PJL SET PAGEPROTECT=LETTER/ LEGAL/ A4/OFF) to put the printer into a page protect mode that reserves the memory equivalent of a complete full-color frame buffer for the current page size. Page protect mode reserves printer memory blocks large enough to represent cyan, magenta, and yellow (CMY) bitmaps for an entire page of the currently selected media).

Noise Dither. Two new halftone render algorithms (noise dither and monochrome noise dither) have been added.

Arbitrary Dither Matrix Sizes. The printer now allows the full 16-bit range for downloaded dither matrix height and width (?*m#W).
