Comment 11 for bug 984082

I had the same behaviour - printing from pdf files was at 100 dpi. In the cups error.log there was a "Using image rendering resolution 100 dpi" information. I found on pdftops sources that 2012-04-10 in change #6926 there was a change for setting a resolution setup in ppd options ('Resolution', 'DefaultResolution'). But my ppd doesn't contains such options.

I found a workaround for my system. I have brother DCPJ315W printer and in original ppd file I have such similar options:

*%==== Resolution Features =================================
*OpenUI *BRResolution/Quality: PickOne
*OrderDependency: 14 AnySetup *BRResolution
*DefaultBRResolution: 600x600dpi
*BRResolution 150x150dpi/Fast: " "
*BRResolution 300x300dpi/Fast Normal: " "
*BRResolution 600x600dpi/Normal: " "
*BRResolution 1200x1200dpi/Fine: " "
*BRResolution 1200x2400dpi/Photo: " "
*BRResolution 1200x6000dpi/Highest: " "
*CloseUI: *BRResolution

I added similar options before this one:

*%==== Resolution auto Features =================================
*OpenUI *Resolution/Quality Auto: PickOne
*OrderDependency: 14 AnySetup *Resolution
*DefaultResolution: 600x600
*Resolution 150x150/Fast: " "
*Resolution 300x300/Fast Normal: " "
*Resolution 600x600/Normal: " "
*Resolution 1200x1200/Fine: " "
*Resolution 1200x2400/Photo: " "
*Resolution 1200x6000/Highest: " "
*CloseUI: *Resolution

Now I have two options in printer preferences: 'auto' for setting pdftops and original BRResolution for Brother's filters.
