[Gimp-print-devel] Canon SELPHY CP1000 misaligned

[Ludwig TAUER]

Hello everybody,
recently my CP-100 was broken, so I replaced it with the
SELPHY CP1000.

Using 'Postcard 100x148mm' the printed image seems to be shifted
approximately 5 mm to the top, thus cutting the top edge and
leaving blank the bottom edge.

Any hints welcome,where to look in the source for corrections.

Greetings from Vienna

The printable dimensions changed a little bit between the older and
newer models, I'd double-check to make sure the aspect ratio of what
you're printing is what it needs to be.

For 'P' prints, it was 1232x1808 (1:1.4675) on old models, and 1248x1872
(1:1.5) on newer models.

Hi Solomon,
I'm using PhotoPrint to generate the images and print.
Comparing the print preview and the actual print, the righy edge is
correctly cut on the real print and the preview shows the full
height.
I let PhotoPrint export the generated image, copied it to a SD card
and printed offline. Surprise! The print is in full height! So that
is a workaround.
Any hints?

Best regards
Ludwig

But if you print directly from Photoprint, it's no good?
That's ...odd.

Can you print something from the GIMP plugin?

I'll see if I can get photoprint to compile (it doesn't like modern GCC)
and recreate this problem. FWIW, I have had no problems printing to old
or new CP-series printers.

I've created a port of PhotoPrint for FreeBSD long ago and it compiles
well even with the latest clang (4.0). The only change is needed is:
---
@${REINPLACE_CMD} -e 's|glib/gstrfuncs.h|glib.h|g' \
${WRKSRC}/gp_cppsupport/gprinter.cpp

Seems to be a bug in PhotoPrint. If I crop image to postcard size
GIMP plugin uses the full printable area. Sorry for the noise.
Too bad my favorite print tool does not properly crop the image to
fit into full printable area. :-(
Again, sorry for wasting your time and bandwith.

PhotoPrint does have its bugs, but as one of the very few direct users
of the Gutenprint libraries, it's uncovered some bugs in Gutenprint too.

So what I'm saying is that this still merits looking into..
