<h1 class="topictitle1">ZFOLD (Z-fold) keyword in printer files</h1>
<div><p>Use this record-level keyword to specify that a z-fold operation
is to be performed on the current sheet. The reference-edge and paper-type
parameters are required.</p>
<div class="section"><p>The format of the keyword is:</p>
<pre>ZFOLD(reference-edge paper-type)</pre>
<p>The
possible values are:</p>
<div class="p"><strong>reference-edge:</strong> <dl><dt class="dlterm">*BOT</dt>
<dd>The reference edge is the bottom edge of the media.</dd>
<dt class="dlterm">*RIGHT</dt>
<dd>The reference edge is the right edge of the media.</dd>
<dt class="dlterm">*TOP</dt>
<dd>The reference edge is the top edge of the media.</dd>
<dt class="dlterm">*LEFT</dt>
<dd>The reference edge is the left edge of the media.</dd>
<dt class="dlterm">*DEVD</dt>
<dd>The reference edge is the default reference edge used by the device.</dd>
</dl>
</div>
<div class="p"><strong>paper-type:</strong> <dl><dt class="dlterm">*LEDGER </dt>
<dd>The paper to be used is ledger-sized (11 x 17 in.).</dd>
<dt class="dlterm">*A3 </dt>
<dd>The paper to be used is A3-sized (297 mm x 420 mm).</dd>
</dl>
</div>
<p>Specify DEVTYPE(*AFPDS) on the CRTPRTF command when
ZFOLD is specified in the file. If DEVTYPE is changed to anything other than
*AFPDS, the keyword is ignored and a warning message is issued at print time.</p>
<p>If
ZFOLD is specified for a printer that does not support z-fold operations,
the value specified for FIDELITY in he printer file controls whether the file
prints.</p>
<p>ZFOLD is ignored at run time if it is not specified on a page
boundary. The printer is on a page boundary when no named or constant fields
are processed for a page. After a named or constant field is processed, the
printer is no longer on a page boundary. The printer is on a page boundary
again when a SKIP, SPACE, or ENDPAGE keyword is processed that causes the
printer to move to a new page.</p>
<p>ZFOLD, SKIP, and SPACE keywords are processed
in the following order:</p>
<pre>SKIPB
SPACEB
ZFOLD
SPACEA
SKIPA</pre>
<p>ZFOLD is in effect only for the record format specified. For
the record format in which ZFOLD is specified, the page size is changed to
the size of the paper-type specified for ZFOLD: ledger or A3. After records
with the specified record format are processed, the page size for the next
record format (if the ZFOLD keyword is not specified) is the page size specified
at the file level (CRTPRTF, CHGPRTF, or OVRPRTF command).</p>
<p>ZFOLD is in
effect for just a single sheet. If consecutive sheets are to have a z-fold
operation applied, then ZFOLD must be specified for each sheet. Printers
can support a varying maximum number of sheets number of sheets per spooled
file that have had a z-fold operation applied to them. Check your printer's
hardware reference for this information.</p>
<p>The reference edges supported
by a printer vary. Check your printer's hardware reference for this information.</p>
<p>The z-fold operation causes the current sheet to be first
folded in half inwards (so the front side of the sheet is now inside the fold)
along a line parallel to the reference edge. The half of the sheet furthest
from the reference edge is again folded in half outwards along a line parallel
to the reference edge. For example, when applied to an 11 x 17 in. sheet with
the reference edge along a short side, the result is an 8.5 x 11 in. foldout.</p>
<p>This
finishing operation is applied to each medium, or sheet.</p>

<div class="section"><h4 class="sectiontitle">Example</h4><pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
A*
A R REC1 ZFOLD(*DEVD *LEDGER)
A*</pre>
<p>When REC1 is printed, it is z-folded by the printer's post
processor.</p>
<p>Only one ZFOLD keyword for each record format is valid at
any time. Even with option indicators, specifying more than one ZFOLD keyword
per record format is not valid.</p>
<p>The overflow line number is recomputed
if you specify ZFOLD, because the page size is either ledger or A3. The new
overflow line number maintains the distance between the overflow line and
the bottom of the page as specified in the printer file. The overflow number
specified in the printer file will be restored when processing is complete
for ZFOLD. So if the file level specifies an overflow line which is 1" from
the bottom of the page, the overflow line for a page on which ZFOLD is specified
is also 1" from the bottom of the page.</p>
<p>Refer to your printer's documentation
for additional information about the z-fold operation.</p>
<p>Option indicators
are valid for this keyword.</p>

<div class="section"> <div class="note"><span class="notetitle">Notes:</span> <ol><li>Use of this DDS keyword causes an <span class="keyword"><font color="Purple">i5/OS™</font></span> spooled file to be generated so that it is
not correctly printed when sending the spooled file to MVS™. The spooled
file does not print and is held on the output queue by PSF/MVS.</li>
<li>Feature Print
Services Facility™ (PSF) is required for use of this keyword. If PSF is
not installed, you will not be able to print files on a IPDS™ printer using
