<h3 id="rzau6thru">IPDS pass-through</h3>
|
||
|
|
<p>Before printing, SNA character string (SCS) files are converted to Intelligent Printer Data Stream™ (IPDS™) files. These are then converted to Advanced Function Presentation™ data stream (AFPDS), and
|
||
|
|
then to printer-specific IPDS. Also, IPDS files are converted to AFPDS, then are
|
||
|
|
converted to printer-specific IPDS. The final IPDS files have specific commands for your
|
||
|
|
printer. You can choose to skip the conversion to AFPDS and to printer-specific IPDS. This is called IPDS pass-through. IPDS pass-through is specified on a PSF configuration
|
||
|
|
object.</p>
|
||
|
|
<p>Specifying IPDS pass-through in the PSF configuration object allows only those spooled
|
||
|
|
files eligible for IPDS pass-through to bypass the extra transforms. Those
|
||
|
|
spooled files not eligible for IPDS pass-through are still transformed to
|
||
|
|
AFPDS and then to printer-specific IPDS.</p>
|
||
|
|
<p>This figure shows the data stream origination, flow, and conversion for
|
||
|
|
a spooled file when IPDS pass-through support is enabled.</p>
|
||

<img src="rbaft525.gif" alt="Data stream origination, flow, and conversion for a spooled file when IPDS pass-through support is enabled" /></div>
|
||
|
|
<p>Consider using IPDS pass-through if one of these apply: </p>
|
||
|
|
<ul>
|
||
|
|
<li>You have applications that generate SCS or IPDS data streams when printing to an Advanced Function Presentation (AFP™) printer.</li>
|
||
|
|
<li>You are using applications such as the IBM® Business Graphics Utility for AS/400® licensed
|
||
|
|
program, GDDM®, or Virtual Print that do not support AFPDS.</li>
|
||
|
|
<li>Your SCS or IPDS application does not contain any reference to overlays
|
||
|
|
or to host font character sets.</li></ul>
|
||
|
|
<p><span class="bold">Limitations of IPDS pass-through</span></p>
|
||
|
|
<p>These IPDS pass-through limitations determine whether a spooled file or printer
|
||
|
|
is eligible for IPDS pass-through: </p>
|
||
|
|
<ul>
|
||
|
|
<li>Some SCS or IPDS spooled files are not eligible for IPDS pass-through.
|
||
|
|
One such situation is when they contain special functions that require being
|
||
|
|
transformed to AFPDS for the spooled file to print correctly.
|
||
|
|
<p>Spooled
|
||
|
|
files that contain the following data or printer file attributes are not eligible
|
||
|
|
for IPDS pass-through: </p>
|
||
|
|
<ul>
|
||
|
|
<li>For SCS or IPDS data streams, the data stream contains Image Object
|
||
|
|
Content Architecture (IOCA) or IM1.</li>
|
||
|
|
<li>For SCS or IPDS data stream, a front or back overlay was specified
|
||
|
|
in the printer file.</li>
|
||
|
|
<li>For SCS data stream, IGCDTA(*YES) was specified in the printer file.</li>
|
||
|
|
<li>For SCS or IPDS data streams, MULTIUP with REDUCE(*NONE) was specified
|
||
|
|
in the printer file.</li>
|
||
|
|
<li>For SCS or IPDS data stream, a form definition was specified in the
|
||
|
|
printer file.</li>
|
||
|
|
<li>The EDGESTITCH or CORNERSTPL finishing operation is specified in the printer
|
||
|
|
file.</li></ul>
|
||
|
|
<p>If IPDS pass-through is specified but the spooled file is
|
||
|
|
ineligible, a diagnostic message is sent and the spooled file is processed
|
||
|
|
as usual. It is transformed to AFPDS and then to printer-specific IPDS.</p></li>
|
||
|
|
<li>IPDS pass-through support is available for any IPDS printer that provides resident fonts.
|
||
|
|
This is because the resident fonts referenced in the data stream must be mapped
|
||
|
|
to the host fonts, which are downloaded to the printer. Therefore, IPDS pass-through
|
||
|
|
support is not available for these IBM IPDS printers: 3820, 3825, 3827, 3828, 3829,
|
||
|
|
3831, 3835, and 3900-001.
|
||
|
|
<p>When a printer writer is started to an AFP(*YES)
|
||
|
|
printer that does not support IPDS pass-through and IPDSPASTHR(*YES) is specified,
|
||
|
|
a diagnostic message is sent. The spooled file is transformed to AFPDS and
|
||
|
|
then to printer-specific IPDS.</p></li></ul>
