cups printing an offset

I am using an up to date Gentoo Lynux system, but got here using the link from www.cups.org to report Bugs in Linux.

I have discovered what I think is a bug in net-print/cups-1.6.2-r5
All printing has an X offset of -3mm and a Y offset of -20mm
My printer is a Lexmark X543 network printer.
Previewing printing is normal in for instance LibreOffice or a PDF in Evince. but when printed to the Lexmark printer there is the offset. Same offset when printing a test page.

I downgraded to version net-print/cups-1.6.3-r2 with the same result.

I then downgraded to version 1.5.3 which uninstalls net-print/cups-filters-1.0.34-r1 and app-text/qpdf-4.1.0:0/10 and printing is back to normal.
