    Description                       
     
       This utility will enable you to print the contents of  your  IBM PC  or
       PC/XT display screen to either the Hewlett-Packard LaserJet or ThinkJet
       printer.  Once installed, the utility will automatically be loaded into
       memory each time your computer is booted up.   It is executed using the
       normal sequence of keystrokes  (Shift and PrtSc)  used in  transferring 
       the contents of your display screen to a printer.   Use of the  utility
       is fully described in this document.

    Installation

    LaserJet Printer  

       1.  Copy the file 'LASERJET.EXE'  or  'HERCULES.EXE'  (for the Hercules 
           high-resolution graphics board)  from the print screen utility disc
           to your operating system disc.   Refer to  your  IBM PC  DOS  users
           guide for instructions on the use of the 'COPY' command.

       2.  Add the command  'LASERJET A'  or  'HERCULES A'  (for the  Hercules
           high-resolution graphics board) to your  AUTOEXEC.BAT  file.   When
           executed, this command will automatically  load  the  print  screen
           utility into memory.   Refer to your  IBM PC  DOS users  guide  for 
           instructions on using and maintaining 'BATCH' files.

           The following commands must be in your  AUTOEXEC.BAT  file to  help
           insure proper execution of the print screen utility:

                 MODE COM1:9600,N,8,1,P
                 MODE LPT1:=COM1
                 LASERJET A or HERCULES A

       3. Reboot your computer to automatically execute the  commands  in  the
          AUTOEXEC.BAT file and load the print screen utility into memory.



    ThinkJet Printer  

       1.  Set the switches on the back of the ThinkJet Printer as follows:

                    Switch bank 1                     Switch bank 2
            (parallel and serial printers)        (serial printers only)

         1    2    3    4    5    6    7    8      1    2    3    4    5  
       down down down down down  up   up  down    up  down down down down

           Note: Because of increased  availability  of  software  drivers  to 
                 support the ThinkJet Printer in an HP mode,  we now recommend
                 the above configuration for Centronics printers  on  the  IBM 
                 PC.   This may be different  from  what  is  listed  in  your 
                 ThinkJet Owners Manual.

       2.  Copy the file 'THINKJET.EXE'  or  'HERCULES.EXE'  (for the Hercules 
           high-resolution graphics board)  from the print screen utility disc
           to your operation system disc.   Refer to  your  IBM PC  DOS  users
           guide for instructions on the use of the 'COPY' command.

       3.  Add the  command  'THINKJET'  or  'HERCULES A'  (for  the  Hercules
           high-resolution graphics board)  to your AUTOEXEC.BAT  file.   When
           executed, this command will automatically  load  the  print  screen
           utility into memory.  Refer to your  IBM PC  DOS  users  guide  for 
           instructions on using and maintaining 'BATCH' files.

           The following commands must be in your  AUTOEXEC.BAT  file to  help
           insure proper execution of the print screen utility:

                 MODE COM1:9600,N,8,1,P     (serial ThinkJet Printer only)
                 MODE LPT1:=COM1            (serial ThinkJet Printer only)
                 THINKJET or HERCULES A

       4. Reboot your computer to automatically execute the  commands  in  the
          AUTOEXEC.BAT file and load the print screen utility into memory.







    Using the Print Screen Utility (either printer)

    Basics  

       If you are using LOTUS 1-2-3,  please  read  the  next  section  before 
       attempting to use the utility.   When used with most software  programs
       the utility is executed  by  pressing  the  'Shift'  and  'PrtSc'  keys 
       simultaneously.   Notice that an  'A'  will appear in  the  upper  left 
       corner of the screen indicating that alphanumeric data is to be printed 
       or a '-' if graphics is to be printed.

    Use with LOTUS 1-2-3  

       When used with LOTUS 1-2-3,  additional input is required to  tell  the 
       utility what type of data is to be printed.   First press  the  'Shift'
       and 'PrtSc' keys then immediately follow them by pressing the  'G'  key
       then the 'C' key.   These options are described in the next section  on
       printing options.                                                      


    Printing Options   

       Although not required,  several printing options are available with the
       utility.  If you wish to use any of the following options, they must be 
       entered within five seconds after  pressing  the  'Shift'  and  'PrtSc' 
       keys.   Only one option from each group  (orientation,  print  position
       and paper ejection)  may be selected.   The printing process will begin
       five seconds after the last key is pressed.


            Group         Key            Option
            -----         ---            ------

        Orientation       * P       Portrait (LaserJet only)
                            L       Landscape (LaserJet only)

        Print Position    * T       Top half of page
                            M       Middle of page
                            B       Bottom half of page

        Paper Ejection    * Y       Form feed at end of print
                            N       No form feed at end of print

       * indicates default value

       Note: When used on the LaserJet printer,  the  utility  can  print  one
             graphics screen and one alphanumeric screen on the same page  but
             cannot print two graphics screens on the same  page  due  to  the
             memory limit of the printer.  However,  two graphs can be printed
             on the same page by first printing one  graph  using  the default
             options, then manually feeding the same page through the  printer
             for the second graph  (this time using the  'B'  (bottom of page) 
             option).   Refer to your LaserJet owners guide  for  instructions 
             using the manual feed feature of the printer.

       When the utility is used with most software programs  it  automatically
       determines the contents of the screen information to be printed.   When
       the utility is used with a software program that does not provide  this 
       information (LOTUS 1-2-3  for example),  you  must  supply  it  to  the 
       utility through printing options.   If your output is not  as  expected 
       after first attempting to print  your  screen  using  the  'Shift ' and
       'PrtSc' keys, try the following options.   These  options  are  entered
       within five seconds after pressing the 'Shift' and 'PrtSc' keys.

            Group         Key            Option
            -----         ---            ------

        Screen content     A       Alphanumeric screen     
                           G       Graphics screen           

        Graphics color     C       Color graphics
                           W       Black and white graphics

        Characters/line    4       40 characters per line   
                           8       80 characters per line      



    Use with a Hercules High-Resolution Board  

       Using the  print  screen  utility  with  the  Hercules  high-resolution 
       graphics  board  is  performed  using  the  same  procedures  described       
       earlier.   However,  because this board allows for the storage  of  two
       'pages' of graphics images, a printing option is provided to allow  for 
       selection of either page of graphics image.   Enter a '1' for the first 
       page of graphics image or a '2' for the second page.   Also,  the 'C/W'
       option is not available when the Hercules board is used.



    In Case of Difficulty  

    Nothing Prints  

       Insure that the printer and  computer  have  been  configured  together
       correctly, refer to your owners manual for information  on  configuring  
       the printer to your computer.   Next insure that the utility  has  been
       installed correctly per the  installation  portion  of  this  document.
       Finally, insure that your printer is on-line.

       Insure that this print screen utility is the  only  one  that  you  are  
       attempting to use.   For example, an IBM program called  'GRAPHICS'  is
       used for printing to  an  IBM  color  printer  and  will  not  work  in 
       conjunction with this print screen utility.   Check  your  AUTOEXEC.BAT
       file for any command that may appear to load another print utility, and
       delete it from the file.
 
    Image Printed But Not Correctly  

       The software creating the image may  not  be  providing  the  necessary
       information to the print screen utility as is the case with  LOTUS 123.
       Try using the options which describe the contents of the screen to  the 
       utility as described in the options section.








    Error 22 (buffer overflow) occurs when using  a  Hercules  high-resolution 
    board and the LaserJet printer   

       The graphics image to be printed is too complex and must be simplified.
       Elimination of a border if used may help in eliminating the problem.
