Bug Description

Binary package hint: cups

I am using Ubuntu Jaunty 9.04 on amd64.

Every time I print an image through The GIMP or eog, the completely transparent areas are printed in black.

Steps to reproduce:
1. open a .png image with alpha areas in The GIMP or eog
2. print it

Expected result: completely alpha areas are "white" (there should be no ink in these areas)
What happens: completely alpha areas are #000, complete black.

The printer I am using is an Epson Stylus Photo R220, and this problem was not present in Intrepid.
I can reproduce it with every printing quality (economy, 360dpi, 720dpi,...), rgb or greyscale.

I also see this issue when printing a transparent SVG using an HP Photosmart D7260. Interestingly, print preview shows a white background when using Eye of Gnome, but the background is printed as solid black. I also tried setting White as a custom colour from within Preferences -> Image View -> Transparent Parts, but this did not help.

Can you also attach the error_log of CUPS, following the instructions in the section "CUPS error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems? Thanks.

Problem is Ghostscript. If you capture the PDF output of eog or print into a PDF file from eog and then try to display the resulting PDF with Ghostscript, you get a black background. Ghostscript is also used to render the file when printing with non-PostScript printers.

It is most likely the following upstream bug of Ghostscript:

This bug is perhaps a duplicate of bug 196009.

Also the attachment of this bug is treated correctly by Ghostscript 8.70, to be released next week. So this bug is really a duplicate of bug 196009.
