Portable photobooth to print 2 identical photo strips #149

Open ctrlw opened 5 years ago

Thanks for this project! I used it to build a photobooth for a wedding in Spain, with 2 main goals:

It was a success, the couple got a nice guest book, people had fun and were queuing up to take pictures, and some even said it was more fun than the other photobooths they had seen at weddings. That's great, as it took a lot of time preparing this and babysitting it at the party.

Thanks for sharing!

I have resolved most printing issues by switching to pycups and connecting the CP1300 via wifi using the airprint protocol. Have you tried that?

ctrlw commented 5 years ago

No, but I'll try pycups the next time. I'm surprised that wifi is more stable here than a USB connection.

From my local modifications I'd recommend to take the bicubic image resizing into the main repository, and created a pull request. This greatly improved resulting image quality, e.g. for people with glasses. I didn't notice a performance impact, but my original photos were already very small (640x480). If performance is a concern, maybe it could be offered as a configuration.

The main difference between USB and WiFi printing is the used PPD file: with WiFi, the picture file is sent to the printer and processed there for printing while with USB, the picture file is processed on the RPi and then send to the printer. I think that is responsible for some of the delay and is the reason that printing via Wifi yields a better quality.

We should definitely change to bicubic resizing, thanks for that!

Hello ! what did you change to have 2 identical band?

I can not do it maybe I'm too stupid .....

I have a single strip in the middle of the sheet print! it may be due to the 90 ° rotation of the camera?

Hi thyristor59,

Did you use my branch? I did a few changes based on the official development branch at the time. You can simply take it and it should directly work, at least if you have a similar setup: https://github.com/ctrlw/photobooth/tree/development

You can also just view my code changes and adapt the code yourself: https://github.com/reuterbal/photobooth/compare/development...ctrlw:development

I managed to have 2 identical bands! thank you ! now the format is not excellent! Remember the settings of the application you had changed? in advance again thank you!

ctrlw commented 5 years ago

The settings are also in my branch, as I changed the default settings file.

I used the selphy’s standard format 10x14.8cm prints, and 640x480 images from the raspicam.
