New Adaptive compression system enables the printer to
compress internal raster data when memory becomes low.
This operation occurs automatically; there are no PCL
commands for this feature (refer to Chapter 5 for ADC
information).
New Allows PCL jobs to be printed (using LocalTalk or
EtherTalk MIO) using AppleTalk protocol.
Modified Supports 1-32,767 copies as does the HP LaserJet IIISi
printer.
New Allows selection of the units of measure for cursor moves,
drawing rules, and for character spacing (font metrics).
Modified A parameter value is added for B5 envelope size; the HP
LaserJet 4 printer supports the four standard paper sizes
and five envelope sizes.
New Header Printer will expand 300 dpi bitmap fonts to 600 dpi. A new
300/600 dpi bitmap font descriptor has been added to
allow bitmap fonts to be created that work at either 1/300
or 1/600 inch printer resolution.
New Header A new Universal header has been added to allow design of
typefaces of different scaling technologies to be supported
by one header. This header is used to support TrueType on
the HP LaserJet 4 printer. (This header will be used to
support any other new scaling technologies HP may add in
the future).
New TrueType scaling technology support has been added to
the printer.
New Several new Intellifont and TrueType internal typefaces
(and supporting symbol sets) are now provided in the
printer.
Modified Parameter values have been added to support raster
resolutions of 200 dpi and 600 dpi.
New Header A new 300/600 dpi user-defined pattern header has been
added to support patterns that work at either 1/300 or
1/600 inch printer resolution.
