New page

==Overview==
SNA Communications Server (formerly VTAM) Printer Support (VPS) feature, which is available for the IBM z/OS operating system, lets you direct output to a SNA Communications Server printer, utilizing the USE command. The creation and maintenance of a print queue is accomplished by formatting a Model 204 file's Table D pages into multiple print queues. 
A request is the spooled output produced from a USE command. 
The VPS feature uses two types of pages:
<ul>
<li>Definition pages are the individual print queue definitions. Each print queue definition has two types of print request pages chained from it.</li>
<li>Print request pages are of two types:
<ul><li>Requests waiting to print</li>
<li>Requests waiting to purge</li></ul>
</li>
</ul>

Each print queue is assigned a unique SNA Communications Server printer definition. For each SNA Communications Server printer definition, a subtask is attached that handles all communications between Model 204 and the SNA Communications Server printer.
The printer daemon manages the interaction between the print queue and SNA Communications Server printer subtask. The printer daemon is an IODEV=3 user running as a pseudo-subtask.

The VPS system does the following:
<ul>
<li>Lets you direct output to SNA Communications Server type TTY and 328X printers utilizing the USE command.</li>
<li>Makes available a print queue for spooling and maintaining USE print requests.</li>
<li>Provides commands to display the status and control the destination of VTAM USE requests.</li>
</ul>

==Initializing SNA Communications Server printer support==

Use the following JCL to initialize SNA Communications Server printer support on the z/OS operating system:
<nowiki>//CCAPRQ DD DSN=MODEL204.PRINT.QUE,DISP=SHR PRINT QUE FILE
//CCAIN DD *
:
:
:
VTPRNAME=M204PRT,SPOOLOPT=1 VTAM APPLID and AUTO INIT. CCAPRQ
IODEV=3,LECHO=1,INPUT=DAEMONI,OUTPUT=DAEMONO
:
:
/*
//DAEMONO DD SYSOUT=*
//DAEMONI DD * IODEV 3 INPUT
LOGIN USERID
PASSWORD
CREATEPQ FORMAT CCAPRQ TO BE USED AS A PRINT QUE
THIS CAN BE ELIMINATED WITH SPOOLOPT=1
DEFINE PRINT QUEUE DEFINE INDIVIDUAL PRINT QUEUES
DEFINE VTAM PRINTER DEFINE VTAM PRINTERS
PRTQDAEMON START THE PRINT DAEMON
/*
</nowiki>
==Spool control==
SPOOLOPT: Print queue spooling options:
<blockquote>
