When you are running Pass Thru for a spooled printer, there
are three ways you can close your spool file and send it to the
printer without interrupting your Pass Thru session:
The PRT option, which you specify in the PTCONFIG file,
sets a receive timer (from 0 through 28800 seconds) for the HP 3000 printer.
If the timer expires before data has been received from the IBM
host for that printer, Pass Thru closes the current spool file and opens
a new spool file to continue receiving data from the host. Output
from the closed spool file can then be printed. The PRT option is used with LU.T1 and LU.T3 sessions.
The PRT option is described in Chapter 2 “Configuring Pass Thru”
The CLPRT softkey, which you configure in the PTCONFIG file, closes
the current spool file and opens a new one. The CLPRT softkey is used with LU.T2 sessions. See "User-Defined
Softkey Functions," in Chapter 5 “Using Terminals with Pass Thru” for
information on the CLPRT softkey. For information on configuring the
CLPRT softkey, see Chapter 2 “Configuring Pass Thru”
The SEND CLOSE request, described later in this chapter under "Entering
Printer Commands and Adjusting Page Length," closes the
current spool file and opens a new one. The SEND CLOSE request is used with LU.T1 and LU.T3 sessions.
SNA IMF automatically closes the spool file when an UNBIND
is received for the LU-LU session.
On MPE V, if a system line printer is acquired by SNA IMF/V
as unspooled, no other MPE user may access that printer until either
the SNA IMF communication line to the host is shut down or the Pass
Thru program ends or is released. SNA IMF/XL does not support unspooled printers.
