Errant bands of whitespace with AFP Driver psegs


Question

Sometimes when I include psegs from the Windows or OS/2 AFP driver the psegs don't print correctly. There are lines of white space through them.

Answer

 You will see this with IOCA image.
 Your document uses units of 240 for positioning items on the page.
 The page segment uses units of 1440 for positioning its data, while
 the data itself is in 300 dpi. IOCA page segments inherit the units
 of their owner for POSITIONING.

 The first piece of the image is positioned at 0,0 so it is placed
 correctly on the page.  The second piece is positioned at, say,
 0,720 (.5 inches down from the first piece).  BUT,
 the 720 is converted to 240ths and causes the second piece
 of the image to be placed 3 inches down the page. This leaves the
 large band of white you see between the 2 pieces.

 How to get around this:
 1. Both the Pennant AFP PM Printer Driver for OS/2 Version 1.00 and
 and the Pennant AFP Printer Driver for Windows Version 1.04/1.14
 contain a fix to write the image out as one piece and output
 is as expected.
 2. When scripting, format for DEV(AFPx). Your LISTAFP output will
 be in 1440ths so the units of measure in the pseg will be interpreted
 as expected.
