Thank you,

So far it doesn't work... but I'll play with it.  I applied the style to the class="page article" element, and to the one child below the page element (a table). In both cases it showed the content rotated 90 degrees in the web preview, but not in the final printed PDF.

Perhaps that's a CSS property not supported well by wkhtmltopdf?

Thanks,

John

Update:

The solution requires a blend of Odoo Tools' and Anu's answers.  In experimenting, I found that the version of wkhtmltopdf used by hosted Odoo 11 does not support transform unless it is prefixed. It uses webkit to render, so this *does* work in the preview, and in print:

<div class="page article" style="transform: rotate(90deg); -webkit-transform: rotate(90deg);">

What made this confusing is that the non-prefixed property works fine in the preview, because of course I'm using a current browser.

Hi,

   use this css

.rotate {

/* Safari */
-webkit-transform: rotate(90deg);

/* Firefox */
-moz-transform: rotate(90deg);

/* IE */
-ms-transform: rotate(90deg);

/* Opera */
-o-transform: rotate(90deg);

/* Internet Explorer */
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3);

}
