To Pascal Obry:

I have done some tests, and printing applying my custom printer profile,
with relative colorimetric intent, and black point compensation enabled,
works completely Ok.

I cannot see any difference respect to printing the same picture with
the aplied externally with tfiicc to an exported image.

And in this later case, I connot see any diference when I open and print
the already profiled image with darktable respect the same file opened
and printed form GIMP  (2.9.1 developement version from
ppa:otto-kesselgulasch/gimp-edge)


I have an isuue with another Epson printer, an A4 Epson SX-445W atached
to the same computer (by WiFi) and using the Gutenprint driver. In this
printer the prints from Darktable look ok, but they are a lot smaller
than the size adjusted in Darktable. When I print to the same printer
from GIMP, the image size is correct,

But this only happens to me with this printer. My A3+ printer, an Epson
WF-7515 (the one that I have reprofiled for Darktable and used to do all
the test described above) prints with the exact size I adjust in
darktable's print module. And the setup is, as far I can see, very
similar with both printers. But the print size does not match in the
smaller printer...


I need to investigate it further. But if you already have any clue about
the possibly reason for this size difference, or the best way to debug
it, I would appreciate very much any help.

Thanks
