Controlling 3270 Emulation
Controlling Printer Sessions
The Control Printer Sessions dialog box provides the following push
buttons:
<Change Status>
Choose this to enable a disabled session or to disable
an enabled session. (For more information, see
“Enabling and Disabling a Printer Session”.)
<Done>
Choose this to exit the Control Printer Sessions dialog
box.
Enabling and Disabling a Printer Session
To conduct printer emulation, you must enable a printer session. To
toggle a session's status between enabled and disabled, use the following
procedure:
Step 1. Select a printer session in the Control Printer Sessions dialog box.
Step 2. Choose <Change Status>.
Once enabled, a printer session is available to direct 3270 output either
to a printer attached to your HP-UX computer or to a file on the HP-UX
computer. No display function is associated with printer sessions.
For printer sessions associated with display sessions, the TN3270
emulation program automatically disables the printer session unless the
display session is active. If you attempt to enable a printer session
associated with a display session when the display session is not active,
the TN3270 emulation program displays an error message that indicates
that the printer session is not enabled.
Maximum Print Position for LU 1 and
Unformatted LU 3 Printer Sessions
When the host sends data for a printer session, it can specify the
maximum number of characters to be printed on a line (the 'maximum
print position'). The default value is 132; the TN3270 emulation program
accepts any value from the host up to 132, but will reject larger values.
If you need to accept larger values specified by the host, or to restrict the
host to values below 132, you must set the environment variable
SNALU1MPP before starting the TN3270 emulation program. This should
be set to the maximum number of characters acceptable per line (the
