FEATURES OF HEWLETT-PACKARD HPPCL5E PRINTER DRIVER 

****************************************************************

The Hewlett-Packard HPPCL5E Printer Driver version V1.18 includes 
support for the HP LaserJet 4/4M, 4L & 4Si/4Si MX printer and the 
following new features:

Support for Graphics Quality.

    For the LaserJet 4/4M and 4Si/4Si MX, at 600 dpi mode the 
    driver supports 600, 300, and 150 dpi.  For the LaserJet 4/4M,
    4L, and 4Si/4Si MX, at 300 dpi mode the driver supports 300,
    150, and 75 dpi. The actual graphics resolution settings are 
    denoted by the descriptive terms of Low, Medium, and High 
    rather than the actual dpi.

Support for the internal Intellifont typefaces.
    All the internal Intellifont typefaces in the HP LaserJet 
    4/4M, 4L, and 4Si/4Si MX printers are supported in the 19U 
    symbol set.  To obtain WYSIWYG results, use HP Intellifont 
    which supports on-the-fly screen fonts to match your printer 
    fonts in Windows 3.1.

Support for HP-GL/2
    Support for HP-GL/2 is in the HPPCL5E driver.  Under the 
    Options Dialog in the Printer Setup, an option of "Graphics 
    Mode" is available.  Two options are present:  HP-GL/2 or
    Raster.   The first choice enables HP-GL/2 which will 
    increase print performance.  The second choice uses raster 
    only.  The default graphics mode is set to raster for the
    HP LaserJet 4L.  The default mode is set to HP-GL/2 
    for the HP LaserJet 4/4M and 4Si/4Si MX.

    For the HP LaserJet 4/4M and 4Si/4Si MX, if you encounter 
    print difficulties in the default Graphics Mode, it is 
    recommended that you change the mode to Raster and try your 
    print job again. Additional information on this topic may be 
    found in the help files that accompany this driver.  Choose 
    Help from the driver dialog screens or the HP font installer 
    screens to access the HELP information.

Support for EconoMode (Supported only by the LaserJet 4L) 
    Support for EconoMode is in version V1.18 within the 
    Options Dialog.  There are two options available, on 
    or off.  With EconoMode enabled the output will resemble
    draft mode, using fewer dots in order to conserve toner.

Support for Print Density (Supported only by the LaserJet 4L) 
    Print density support is provided in the Options Dialog.  
    Adjust the density of the printer according to the desired 
    density.  The density range is one (lightest) to five 
    (darkest).

Dialog Support for REt
    Another feature added to the Option Dialog is the REt
    (Resolution Enhancement technology) box.  The options here
    are:  
       Light, Medium, Dark, and Off for the HP LaserJet 4L.
       Printer Default, Light, Medium, Dark, and Off for the HP
	 LaserJet 4/4M.
       Printer Default, ON, and OFF for the LaserJet 4Si/4Si MX.

Dialog Support for Resource Saving (Supported only by LaserJet 
    4Si/4Si MX)
    This feature, added to the main setup dialog box, allows the
    user to tell the printer driver how much memory is set aside
    for the each printer personality (PCL and PostScript). 
    This memory is used for saving printer resources between 
    printer language switching. The range is from 0KB to 99900KB.
