[cups] Brother HL-3140CW started printing misaligned pages

Hi All,

Until recently I was able to use this printer to print perfectly aligned pages 
from PCs running gentoo.  A recent update of to cups-2.1.4, or more likely 
net-print/cups-filters-1.16.4 has caused this Brother HL-3140CW laser printer 
to start printing misaligned pages.

The printed content is cropped at the top of the page by some 13mm and shifted 
to the left by 7mm.

I've been using an ipp URI with the LPR drivers and cupswrapper provided by 



but since the page margins/alignment became screwed up I tried in vain all the 
generic cups drivers in the hope one of them would work.

I also updated cups and cups-filters to versions 2.2.6 and 1.18.0 
respectively, in the hope this problem is caused by some regression bug, but 
this didn't help.

Is there some config file tweak I could implement to get this working again 

PS. I noticed each time I modify a printer using the cups http GUI the 
corresponding ppd file default settings are messed up.  In particular, 
DefaultImageableArea and DefaultPaperDimension are reset to Letter for some 

grep Default /etc/cups/ppd/HL-3140CW.ppd
*DefaultColorSpace: Gray
*DefaultPageSize: A4
*DefaultPageRegion: A4
*DefaultImageableArea: Letter
*DefaultPaperDimension: Letter
*DefaultResolution: 300dpi

Selecting 'Set Default Options' in cups and (re)selecting A4 restores the 
correct setttings:

grep Default /etc/cups/ppd/HL-3140CW.ppd
*DefaultColorSpace: Gray
*DefaultPageSize: A4
*DefaultPageRegion: A4
*DefaultImageableArea: A4
*DefaultPaperDimension: A4
*DefaultResolution: 300dpi

I'm not sure if this is related to my problem by I thought of mentioning it 
just in case.
