Using the Printer Attached to Your 3274
Control Unit
You can print what appears in your host window
on a printer attached to your 3274 Control Unit.
Even if the window is not full size on your
screen, you will get a printed copy of the full size
window.
You may not have this type of printer available
to you. If you are not sure, ask your supervisor
or the person you call for help with using your
computer.
If you are not familiar with this type of printer,
you can about it in the IBM 3270 Information
lJispZay System:
3278
Display Station Operator's
Guide, GA27-2890, before you try to use it.
To print on your control unit's printer:
1. Make sure that the host window you want to
print is active.
If the window is not full size on your screen,
you will get a printed copy of the full size
window.
2. Press the Print key.
The line at the bottom of your screen should
look like this:
D-.nn
If it doesn't, press and hold the Ctrl key and
then press the WSCtrl key. If you still don't
see this, there is a problem with the printer.
