image processing library for CP D70DW

[flx1996]

Hello @all,

I hope somebody can help me. I got a Self-o-mat photobooth from a friend, which works perfect with a Canon Selphy Cp1300 printer. But for me it is to slow, so I get a new Mitsubishi CP D70DW printer, because it should be supported from the self-o-mat. After the installization there is the error: "Image Processing Library not found, aborting!" After many hours of information i found out, it is neccessary to install a image processing library on the Raspberry PI. I would connect me to the raspi, whats possible with cupsuser and the Passwort, but this user has no possibillity to install something because the 'cupsuser is not in the sudoers file'. Can anyone help me out, what I should do to the the new printer work with the self-o-mat?

Thank you in advance! Felix :)

Hi Felix,

how did you install the Raspberry Pi?

Did you use the self-o-mat Base System or start with a fresh Raspberry Pi OS installation?

@ClemensElflein is there any chance that you will bring up the help pages? Certificate is outdated and the link above (copied from the wiki) is broken ("Server Error — 503 — Service Temporarily Unavailable")

I for myself only have experience with Canon SELPHY printers so far.

Hello maehw and thanks for the quick answer,

my best frriend bought the fully build self-o-mat and I got it from him. So he and I didn't install the Raspberry Pi, it based on the self-o-mat system.

Best regards Felix

Hi Felix,

I tried to find more information about the obsolete base system but could not find anything.

The wayback machine only confirmed that this type of printer must have worked before:

"Mitsubishi Electric CP-D70DW

• 400 Bilder pro Rolle
• Günstigerer Druck
• Schneller Druck
• Ausgiebig von uns getestet, bei vielen unserer Kunden im Einsatz - Kompatibilität garantiert!"

You wrote: "After many hours of information i found out, it is neccessary to install a image processing library" — how did you finally find out? Can you paste the exact error message with some more context? Are you sure that this error message only comes up with the Mitsubishi printer and not also with the Canon printer?

Cheers

Hi

Watch here : https://www.peachyphotos.com/blog/posts/201610061508-mitsubishi-cp-d70-family-working/ This patch fixed the problem on my RPi4 with CPCD80DW

Cheers

Hey @BermudaStudio

as you can see on the screenshot, putty tell me "command not found". I login as "cupsuser". Did anyone know whats the problem? Or did anyone know the password of the "pi" user?

[ClemensElflein]

It has been some time since I made this image, try [password redacted for security reasons, message me for the password] as password for the Pi user

Hey @ClemensElflein

It worked. I´m now logged in. Thank you. What should I do now to run the Mitsubishi CP-D70DW printer?

[ClemensElflein]

I honestly can't remember, sorry. Getting those sublimation printers to play nice with Linux was a hassle which involved trying different drivers and reading forum posts. It was also different for each model, even from the same Manufacturer. We tried to include many libs but apparently yours is not shipped with the image.

[flx1996]

I buyed this printer because it was listed in the supported printers on github.

[flx1996]

Also with the "pi" user the same trouble: command not found.

Hi, I'm not a Linux specialist, but this worked for me several years ago :

http://www.peachyphotos.com/blog/posts/201610061508-mitsubishi-cp-d70-family-working/

git clone https://git.shaftnet.org/gitea/slp/selphy_print.git
cd selphy_print
make
sudo make install
cd lib70x
make
sudo make install
sudo bash
echo '/usr/local/lib' >> /etc/ld.so.conf.d/local.conf
ldconfig
exit
cd ..
sudo ./mitsu70x testjobs/mitsu_d70x_4x6-8bpp.raw

reboot Cups web interface > administration > add printer > Mitsubishi-d80dw set as default printer

Hope it will help. Rems

Hey @BermudaStudio,

I try to command the first line "git clone https://git.shaftnet.org/gitea/slp/selphy_print.git" and get back "command not found. I don´t know why.

[flx1996]

I think it was necessary to install the Git on raspberry pi. So I did it and try to do the commands.

Now I updated the printer on the cups but the following trouble appears:

Today I used my Mitsubishi DP70DW on my Linux laptop and I installed it using this guide, which worked (with a small change): https://www.peachyphotos.com/blog/posts/201610061508-mitsubishi-cp-d70-family-working/

I used the git repo here instead of the one in the guide: git clone https://git.shaftnet.org/gitea/slp/selphy_print

and after running

cd lib70x
make
sudo make install

I had to do one more sudo make install from the selphy_print directory.

I'm using Ubuntu 20.04.

Maybe that works for you as well.
