README for ZEHRaster Plus 
Version 2.0
************************************

ZEH strongly recommends you read the information in this file before installing 
ZEHRaster Plus. The information provided here can affect the installation and
configuration of the software.


*******************
Supported Platforms

ZEHRaster Plus is supported on:

	HP-UX 10.2 (CDE only; support on VUE is not yet available)
	Windows NT 4.0 (with Service Pack 4 or higher)
	Solaris 2.6, 2.7
	AIX 4.3.2
	IRIX 6.4, 6.5
	RedHat Linux 5.2, 6.0


******************
ALL UNIX Platforms

---------------------
Disk space allocation

By default, ZEHRaster Plus will be installed in the /opt volume. If the default 
operating system installation was used, the /opt volume will have only 100 MB 
available for optional software, and ZEHRaster Plus requires at least 200 MB 
for its Temp directory alone. Please make sure that the Temp directory has at 
least 200 MB of disk space available.

Also, the /var volume where the LP spool directories are located will need more 
than the default 100 MB assigned to this volume by a default operating system 
installation. The print files that ZEHRaster Plus generates can be quite large 
and will fill up a small spool directory. Please make sure that the /var volume 
has at least 200 MB of disk space available.

-------------------
Preview and display

The viewing of certain files may be affected by the monitor's resolution and 
color depth.  Changing the color depth from 256 colors to something better 
(e.g., 64K, 24-bit, or True Color) will produce the results a user might 
expect. Also, reducing the resolution from 1280x1024 or 1152x864 to 1024x768 
can help.

SGI IRIX

--------------
LP Queue Setup

IRIX 6.4 and 6.5 installations include Impresario, which is used to set up LP 
queues and which by default assigns particular values to be used with the 
printer. Impresario thus attempts to handle the RTL file passing through the 
queue, interpreting the file as PostScript data. The output that is generated 
is several lines of text on several pages.

To set up the LP queue so that Impresario does not interfere with the files 
ZEHRaster Plus sends:

   1. Change directories to the /var/spool/lp/interface directory. Located in 
      this directory will be a file for each printer on the system.

   2. Open and look at the file for the printer you are using with ZEHRaster 
      Plus. If the file contains the following variables, they need to be 
      changed.

           TYPE=PostScript
           NAME="BSD Printer"
           CONVTYPE=PostScriptFile
           BANNER=0
           RAW=1

      Not all of these variables will be present in every file (depending on how
      Impresario set up the printer). Only the ones present need to be changed.

   3. Edit the file so that the variables set for the LP queue are:

           TYPE=Text
           NAME=
           BANNER=0
           RAW=1

      and remove CONVTYPE so that it doesn't appear.

HP-UX

---------------------------
Desktop Environment Support

ZEHRaster Plus is not currently supported under HP VUE.

--------------
LP Queue setup

When setting up an LP queue for use with the HP DesignJet ColorPro CAD, be sure 
to use a script that does not contain an echo IN; command. For example, the 
dumbplot script contains this command, and when it is used with the LP queue 
that is sending RTL files to the HP DesignJet ColorPro CAD, it generates a 
single page with IN; printed at the top, then a second page with the image.

You can use another script that does not use the echo IN; command. The simplest 
method is to copy the script you are using to another name and comment out the 
line containing the echo IN; command. Then assign your new script to the LP 
queue being used with ZEHRaster Plus.

AIX

-----------------------------
Font display on the interface

The font used is Helvetica, a standard font that contains all the characters 
needed for European local language support. (A different font is used for Asian 
language support.) The interface has been designed to accommodate the labels 
and messages in all supported languages. However, the text may appear blocky 
and messages or label text may be "cut off".

If you are having trouble reading the text, stop the application. Edit the
<install_dir>/prg/zplus.reg file to set the font size to a different value. 
The line to edit is:

	FontSize = 10;

so that the font size is either smaller or larger. Save and close the file, 
then start the application again.
