[Gimp-print-devel] print on CD/DVD

[<hra...@gm...>]

Hi, I'm making a tool for printing on CD/DVD tray for linux using CUPS and
the Qt4 libraries (so hopefully also mac). I have an Epson Stylus Photo R320
and I've done some testing with the tray and got some problems. I don't know
if I didn't setup the printer correctly or if there are problems with the
driver.

I'm using gimp-print 5.1.2 and CUPS 1.2.12

My printing options:
Inner Diameter: 66pt
Outer Diameter: 335pt
Media size: A4
Page Region: A4
Media Source: CD
Horizontal Adjustment: 0pt
Vertical Adjustment: 0pt
Resolution: Automatic
# Options I dont quite know what they mean so i left it default
Cd Hub size: Normal
Borderless: no

My image options:
Dpi: 360
Width = Height = 1675px
and I'm printing to the rectangle (0,0, 1675,1675) (without margins)

The first problem is that I couldn't change the print size neither the inner
or outer diameter (the size of the print isn't 66pt).
The other problem is about the adjusting of the image, with Vertical and
Horizontal adjustment set to 0, the white inner circle (i think the driver
add it) is centered, but the image is not (i think i have 5mm of
difference). If i change the Vertical and Horizontal adjustment to -5.3 mm
the image is
centered but the cd not (meaning the center of the white circle and thus the
center of the bigger circle).
All let me to believe that it may be a margin problem.

If you didn't understood my problem I can upload some photos of the test.
