Printing a screen

There are two ways to print the session window of a display emulation session:

When you print host graphics (that is, a picture or a bitmap image) the image is scaled. Therefore the aspect ratio of the printed image may be different than the aspect ratio of displayed image.

    Issues with Unix-based operating systems

    The Print Screen function does not work on the AIX platform due to a browser JVM problem on AIX.

    Missing Unix lp command
    Menu/Toolbar fix

    Missing Unix lp command

    The Print Screen function of Host On-Demand uses a programming interface provided by Java, which does not work on some Unix-based operating systems, such as Linux. The implementation of the programming interface uses the Unix lp command, which is not available on some Unix-based operating systems.

    Following is the workaround for this problem:

    1. Log into the system as a superuser.
    2. Open a terminal session to input commands from prompt.
    3. Change directory to the directory where lpr command is stored. Typically, it is /usr/bin. If this is so, type 
       cd /usr/bin
    4. Create a symbolic link with the ln command. Type
       ln -s lpr lp
    5. Log out.
    6. Log in to the system as a user and start a Host On-Demand display session.
    7. Click File > Print Screen.
    8. Delete the string specified for Banner Page Title. By default, it is specified like Print Screen.
    9. Press OK.

    Menu/Toolbar fix

    If the Host On-Demand Print Screen menu and toolbar option does not work on your Unix system when the output is directed to a printer, you can do the following:

    1. Select Print Screen from the menu bar or tool bar of the session.
    2. Select to send the output to FILE and enter a file name.
    3. Use the Unix LPR command to send the file to a network printer. The command syntax is LPR -Pprinterqueue filename, for example, LPR -P51pcl /home/usr.txt.

    Disabling the printing of a marked area

    Normally a user can print a marked area of the screen by following these steps:

    1. Use the marking rectangle to mark an area of the screen (see Marking and unmarking).
    2. To print the area immediately, click File > Print Screen; or
    3. To collect an image of the area and store it in the list of screen images, click File > Print Screen Collection > Collect Screen. Host On-Demand saves an image of the entire screen, but prints only the marked area. See Using Print Screen Collection to capture part of a screen.

    You can disable the printing of a marked area, so that the entire screen is printed (or collected). When you disable this option, Host On-Demand always prints or collects the the entire screen, even if the user has marked an area using the marking rectangle.

    To disable the printing of a marked area, set the HTML parameter markedAreaPrintingEnabled to false in the Deployment Wizard or in your client HTML page. In your client HTML page, add the parameter as follows:
    <PARAM NAME=markedAreaPrintingEnabled VALUE=false>.
