When drivers are written by using UnidrvUI or PS5UI, the Tabloid Extra paper size may be displayed as 11.69 x 18 instead of 12 x 18

Summary

When Tabloid Extra (DMPAPER_TABLOID_EXTRA) is selected as the default paper size, drivers that are written by using UnidrvUI or PS5UI may show the paper size as 11.69 x 18. This value is inconsistent with industry standards as defined by the IEEE Working Group PWG 5101.1. These industry standards define Tabloid Extra as 12 x 18.

Workaround

To work around this problem, do not use the form definition from UnidrvUI or from PS5UI. We recommend that you use a custom form or the form that was loaded into the forms database.
