4.2.4 <strong>CICS</strong> 3270 Client Printer Support<br />
Client printer support is the ability to define a printer terminal on the client<br />
workstation. This support enables <strong>CICS</strong> applications running on the server to<br />
direct output to the client-attached printer. <strong>CICS</strong> 3270 client printer support uses<br />
<strong>CICS</strong> 3270 emulation functions.<br />
You can direct the output to a physical printer attached, for example, to the LPT1<br />
port, or you can specify a command to process the data into a format suitable for<br />
special-purpose printers.<br />
With the <strong>CICS</strong> Client for AIX or <strong>CICS</strong> Client for Sun Systems, you can start the<br />
<strong>CICS</strong> 3270 Client printer support by using the cicstermp command. <strong>The</strong><br />
cicstermp command performs a fixed-size printer emulation of 64 lines by 132<br />
columns and ignores print attributes such as highlight, underline, high intensity,<br />
and color.<br />
<strong>The</strong> <strong>CICS</strong> 3270 Client printer support is invoked by the cicsprnt command when<br />
you use <strong>CICS</strong> Client for OS/2, <strong>CICS</strong> Client for DOS, <strong>CICS</strong> Client for Windows, or<br />
<strong>CICS</strong> Client for Macintosh.<br />
4.2.5 Benefits of Using <strong>CICS</strong> Clients<br />
<strong>CICS</strong> Clients provide you <strong>with</strong> many benefits. Here are some of the main<br />
benefits:<br />
Easy migration <strong>CICS</strong> Clients enable existing <strong>CICS</strong> users to move<br />
easily and inexpensively into client-server computing<br />
in a low-risk way.<br />
Inexpensive hardware You can use existing low-function workstation<br />
hardware for your <strong>CICS</strong> Clients to gain access to<br />
<strong>CICS</strong> applications and data on the <strong>CICS</strong> for AIX<br />
servers.<br />
Protected investment <strong>CICS</strong> Clients protect your investment in existing <strong>CICS</strong><br />
applications designed for use <strong>with</strong> 3270 devices by<br />
enabling the EPI to allow these applications to<br />
interface <strong>with</strong> workstation facilities and productivity<br />
aids.<br />
Exploit GUIs With the use of <strong>CICS</strong> Clients, your <strong>CICS</strong> applications<br />
can be optimized by locating the business logic on<br />
the server and the presentation logic on the client.<br />
Thus the usability and productivity of GUIs are<br />
exploited.<br />
Concurrent server access A <strong>CICS</strong> Client can concurrently access multiple <strong>CICS</strong><br />
applications on multiple <strong>CICS</strong> for AIX servers.<br />
Because client applications can access applications<br />
and databases on many servers at the same time,<br />
their power is considerably enhanced. <strong>CICS</strong> users<br />
on the supported platform can write new applications<br />
that use the client-server application server model.<br />
Interface to nonterminal devices <strong>CICS</strong> Clients <strong>with</strong> the ECI offer you a convenient<br />
method of interfacing a nonterminal device, for<br />
example, bar-code readers and image scanners, <strong>with</strong><br />
<strong>CICS</strong> for AIX servers.<br />
