The
3708
uses these rules for selecting a printer whether the local copy is initiated by
the operator or by the host application.
If an application program requires a certain printer for copy output, it can begin a
session by prompting the operator to select a certain printer class. The following is
an example of a prompt message: Select Pri nt C1 ass 79.
The operator can then make the appropriate selection.
Changing the Print ID
The display operator can alter the print ID by using the IDENT key.
To select a new print class, press the IDENT key sequence and key in a two-digit ID
between 70 and 85 when the P __ is displayed in the status line. When the status
line appears over the last line of the application, the cursor is positioned after the P.
When the status line appears in a special status area below the last line of the
application, the cursor is positioned on the last line of the application above the P.
The user enters the new Print ID. When a class ID is entered, the
3708
ensures that
the display is authorized to use at least one printer that is a member of that class.
To select a specific printer, press the IDENT key sequence and key in a two-digit
port number between 01 and 10 when the P _ is displayed in the status line. The
3708
ensures that the display is authorized to use the specified printer.
If the matrix does not permit the display to copy to the selected device or to
members of a selected class, the Input Inhibited Operator Unauthorized (X OP X)
message appears in the status line. The IDENT function ends and the keyboard
locks. The user can press RESET and try the print ID sequence. The print ID
returns to the ID in use before the IDENT function was started. If the selected print
class or printer is authorized and is valid for this display, the print ID changes to
indicate the new ID, and the IDENT function ends.
When the IDENT key sequence is pressed, the display is in print ID mode and the
following rules apply:
• The RESET key and other keys that cause a reset operate normally and cause
the print ID mode to terminate.
• The ATTN key, the DEV CNCL key, and the unsolicited host write operate
normally; however, a
3708
print ID mode terminates when these keys are used.
• All other keys that do not operate when keyboard input is inhibited because the
Input Inhibited What symbol to display and the print ID mode to terminate.
Performing an Operator-Initiated Local Copy
An operator can initiate a local copy operation by pressing the PRINT key sequence
on the display keyboard. The print function can be used when the session owner is
the SSCP and the keyboard is unlocked or when the session owner is the PLU, the
keyboard is unlocked, and the SLU is not in receive state. A local copy cannot be
initiated prior to the establishment of the LU type 2 protocol conversion session.
When the PRINT key sequence is pressed, the "current" print ID that is displayed in
the status line determines to which printer the screen image is sent.
If the printer or all printers in the print class are busy, the Input Inhibited Printer
Busy (X PRTBSy) message is displayed in the status line. Also, if the print ID is a
4-86
