This operation occurs automatically; there are no PCL commands for this feature (refer to Chapter 5 for ADC information).

Allows selection of the units of measure for cursor moves, drawing rules, and for character spacing (font metrics). A parameter value is added for B5 envelope size; the HP LaserJet 4 printer supports the four standard paper sizes and five envelope sizes. 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. 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). TrueType scaling technology support has been added to the printer. Several new Intellifont and TrueType internal typefaces (and supporting symbol sets) are now provided in the printer. Parameter values have been added to support raster resolutions of 200 dpi and 600 dpi. 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. ENWW Printer-Specific Differences 2-5

Printer-Specific Differences 2-5
Table 2-3. PCL Feature Additions for HP LaserJet 4
Feature/Command
Support
Comments
Adaptive Compression System
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).
Configuration Command
New
Allows PCL jobs to be printed (using LocalTalk or
EtherTalk MIO) using AppleTalk protocol.
Number of Copies
Modified
Supports 1-32,767 copies as does the HP LaserJet IIISi
printer.
Units of Measure Command
New
Allows selection of the units of measure for cursor
moves, drawing rules, and for character spacing (font
metrics).
Page Size
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.
Bitmap Font Support
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.
Scalable Font Support
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).
TrueType
New
TrueType scaling technology support has been added to
the printer.
Internal Typefaces
New
Several new Intellifont and TrueType internal typefaces
(and supporting symbol sets) are now provided in the
printer.
Raster Resolution Command
Modified
Parameter values have been added to support raster
resolutions of 200 dpi and 600 dpi.
User-defined Pattern
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.
