<h1 class="topictitle1">LPI (Lines Per Inch) keyword in printer files</h1>
|
||
|
|
<div><p>Use this record-level keyword to change lines per inch within a
|
||
|
|
file.</p>
|
||
|
|
<div class="section"><p>If you do not specify LPI for a record, the LPI value is set from
|
||
|
|
the LPI value on the CRTPRTF, CHGPRTF, or OVRPRTF command.</p>
|
||
|
|
<div class="p">The format
|
||
|
|
of the keyword is: <pre>LPI( 4 | 6 | 8 | 9 | 12)</pre>
|
||
|
|
</div>
|
||
|
|
<p>4,
|
||
|
|
6, 8, 9, and 12 are the valid parameter values.</p>
|
||
|
|
<p>When you use multiple
|
||
|
|
LPI per page, all skip-to line numbers (on SKIPB, SKIPA) become absolute positions
|
||
|
|
(fixed locations on the paper). For example, if the page length is 66 lines
|
||
|
|
and the file LPI value is 6, then the forms are 11.0 inches long. If you indicate
|
||
|
|
that it should skip to line number 48, it skips down 8 inches on the page
|
||
|
|
and prints. If, in this example, you print 24 lines at 6 LPI (4 inches) and
|
||
|
|
then print 24 lines at 8 LPI (3 inches), the 48th line is 7 inches down on
|
||
|
|
the page.</p>
|
||
|
|
<p>In both of these examples, 48 lines are processed.
|
||
|
|
If a SKIPB(55) keyword is used, the first example skips to line 55, based
|
||
|
|
on 6 LPI (55/6 inch down the page). In the second example, a page eject occurs
|
||
|
|
and printing starts on line 55, based on 8 LPI (55/8 inch down the page).
|
||
|
|
A page eject occurs in the second example because 7 inches was printed down
|
||
|
|
on the page. A skip to line 55, based on 8 LPI, is less than 7 inches. Therefore,
|
||
|
|
to print on line 55, the current page must be ejected.</p>
|
||
|
|
<p>Data is processed
|
||
|
|
in a sequential fashion based on location, not on line number. If you use
|
||
|
|
a skip-to to go to a line number that is a location above the current location
|
||
|
|
(even though the line number is greater than the current line number), a page
|
||
|
|
eject occurs. Printing continues on the next page.</p>
|
||
|
|
<p>When using multiple
|
||
|
|
LPI per page, all spacing (SPACEA and SPACEB) is done relative to the current
|
||
|
|
position. For example, if you print 24 lines at 6 LPI (4 inches), and then
|
||
|
|
print 24 lines at 8 LPI (3 inches), the 48th line is 7 inches down on the
|
||
|
|
page. If you then do a SPACEA(4) (LPI is still 8 LPI), you will space down
|
||
|
|
1/2 inch from the last line and be a total of 7.5 inches down on the page.
|
||
|
|
It is recommended that you use SPACEA and SPACEB keywords when you use the
|
||
|
|
LPI keyword.</p>
|
||
|
|
<div class="p">The LPI, SKIP, and SPACE keywords are processed in the
|
||
|
|
following order: <p>LPI<br />
|
||
|
|
SKIPB<br />
|
||
|
|
SPACEB<br />
|
||
|
|
SPACEA<br />
|
||
|
|
SKIPA</p>
|
||
|
|
</div>
|
||
|
|
<p>Thus, the SPACE and SKIP keywords use the new LPI value.
|
||
|
|
The LPI for the next and the following lines print at the LPI value specified
|
||
|
|
on the LPI parameter. This parameter value remains in effect until the next
|
||
|
|
record format processes. At the end of the record format, the LPI value changes
|
||
|
|
back to the file level.</p>
|
||
|
|
<p>The LPI takes effect only on a line boundary.
|
||
|
|
If you change the LPI within a line, the new value takes effect at the end
|
||
|
|
of the line and no diagnostic appears.</p>
|
||
|
|
<p>You cannot specify this keyword
|
||
|
|
on the same record format with BLKFOLD, CPI, or DFNCHR. If you use any of
|
||
|
|
these keywords with LPI, the file is not created.</p>
|
||
|
|
<p>This keyword is valid
|
||
|
|
for IPDS™ printers
|
||
|
|
and printers capable of Advanced Function Printing™ support.
|
||
|
|
A warning message is issued when you specify the LPI keyword in a file created
|
||
|
|
with DEVTYPE(*SCS).</p>
|
||
|
|
<p>The overflow line number (OVRFLW parameter on the
|
||
|
|
CRTPRTF command) is not converted to an absolute position (in inches) based
|
||
|
|
on the file-level LPI value. The overflow condition signals when the overflow
|
||
|
|
position (in inches) is reached.</p>
|
||
|
|
<p>Example: Page length = 66, LPI = 6,
|
||
|
|
OVRFLW = 60 (10 inches).</p>
|
||
|
|
<ul><li>Print 36 lines at 6 LPI (6 inches).</li>
|
||
|
|
<li>Print 16 lines at 4 LPI (4 inches).</li>
|
||
|
|
</ul>
|
||
|
|
<p>After line 52 processes, the overflow condition is signaled.</p>
|
||
|
|
<p>Option
|
||
|
|
indicators are not valid for this keyword.</p>
|
||
|
|
</div>

<div class="section"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|

|

the LPI keyword.</p>

<p>Regardless of the LPI you specify on the CRTPRTF, CHGPRTF,
