I don't see anything in the logs for this job (Job 3, the PNG image).
What should I look for? For a previous postscript job, I see this:
D [20/Jan/2005:16:08:20 +0000] [Job 2] PageSize = [ 312 425 ],
HWResolution = [ 203 203 ]
For Job 3, the closest thing I see is this:
D [20/Jan/2005:16:18:11 +0000] [Job 3] Page = 312x425; 0,0 to 294,413
D [20/Jan/2005:16:18:11 +0000] [Job 3] Searching for profile "200dpi/"...
(... Cache tile stuff excerpted here ...)
D [20/Jan/2005:16:18:11 +0000] [Job 3] Before scaling: xppi=198,
The PPD file defines the following:
(these lines are excerpted from the rest of the PPD)
*PaperDimension Letter/US Letter: "312 425"
*ImageableArea Letter/US Letter: "0 0 294 413"
*Resolution 200dpi/200 DPI: "<</HWResolution[203.2 203.2]/cupsColorOrder
