<h4 id="rzalu3270pe">3270 printer emulation</h4>
|
||
|
|
<p>When configuring 3270 printer emulation on i5/OS, you must decide which
|
||
|
|
communications line protocol to use. The iSeries server supports both binary
|
||
|
|
synchronous communication (BSC) and Systems Network Architecture (SNA) 3270
|
||
|
|
printer emulation. Therefore, the choice is normally dictated by the protocol
|
||
|
|
supported by the zSeries server communications software and controller.</p>
|
||
|
|
<p><span class="bold">BSC 3270 printer emulation</span></p><blockquote>
|
||
|
|
<p>BSC 3270 printer emulation can be used with any zSeries server that
|
||
|
|
supports a 3274 control unit (Model 51C) in a BSC multipoint tributary network
|
||
|
|
using a nonswitched line. BSC 3270 printer emulation supports the following
|
||
|
|
features: </p>
|
||
|
|
<ul>
|
||
|
|
<li>Emulation on any line attached to an iSeries server.</li>
|
||
|
|
<li>Ability to print information received from the host system on any printer
|
||
|
|
normally supported by the iSeries server.</li>
|
||
|
|
<li>Emulation of 3284, 3286, 3287, 3288, or 3289 printers.</li></ul></blockquote>
|
||
|
|
<p><span class="bold">SNA 3270 printer emulation</span></p><blockquote>
|
||
|
|
<p>SNA 3270 printer emulation enables the iSeries server to connect into
|
||
|
|
any existing SNA 3270 network. Any printers attached to the system print information
|
||
|
|
received from the zSeries server. The 3270 emulation session is linked to
|
||
|
|
a printer file, which in turn is linked to a printer device. All 3270 printers
|
||
|
|
are emulated as Logical Unit 3 printers with the exception of the 3287 and
|
||
|
|
3289 printers, which can be emulated as either LU1 or LU3 printers.</p>
|
||
|
|
<p>The difference between LU1 and LU3 printers is essentially the level of intelligence
|
||
|
|
which the zSeries server expects to find at the printer device. If the printer
|
||
|
|
is emulated as an LU1 printer, an LU-LU session can be established with the
|
||
|
|
host. Depending on the host applications, such a printer would be able to
|
||
|
|
fully support SNA character string (SCS) data streams sent to it. If the iSeries
|
||
|
|
server printer emulates an LU3 printer, only an LU-PU session can be established
|
||
|
|
between it and the zSeries server. This could cause unexpected results when
|
||
|
|
using host print applications. For example, if the host application was expecting
|
||
|
|
to communicate with an LU1 printer, the printed output would probably not
|
||
|
|
be correctly formatted in terms of line spacing, page length, and so on.</p></blockquote>
