I imagine that, with just a little modification, it will work for any HP printer.

I’ve only attempted this configuration for my specific HP DeskJet. But for that specific reader, I hope this walkthrough can save you a lot of the research I had to do. In this post, I’ll walk you through how I set up a DIY print server with a Raspberry Pi.Īdmittedly this post is intended for a very specific reader.

When I moved into a new house, it felt like a good time to make the printer work for my and my partner’s Macs, and why not make it wireless too? I’ve had a Raspberry Pi lying around unused for years that seemed fit for the job. Over the last few years, my workaround has been to boot up my ancient Windows laptop, share files to it in one way or another, and then print from there. HP’s official support site doesn’t offer raw driver downloads, only a flakey setup wizard application. But, ever since I stopped using Windows, I have not had any luck installing the drivers for it on my MacBook. It works great, and I have a dragon’s hoard of ink for it. I feel like there’s a setting I’m missing to allow quantmod to connect to Yahoo properly but after extensive Googling for answers I’m stumped.Īny assistance with this would be highly appreciated.I’ve had an old HP printer since college without wireless features. My first thought was that it’s not connecting to the internet to pull the data from Yahoo, but the Raspberry Pi is definitely connected to the Internet and I’m able to ping from the container’s command line. The only issue is that the quantmod getSymbols function won’t pull any data. I found a shiny-server Docker container ( hvalev/shiny-server-arm-docker) that works specifically for ARM devices such as the Raspberry Pi, and it works great for self hosting my app. The app works great in RStudio as well as when published on shinyapps.io but the memory restrictions on the free tier of shinyapps.io made me want to self host the app in a Docker container.

I created a Shiny app that pulls and graphs historical stock prices using the quantmod library’s getSymbols function that gets the data from Yahoo Finance.

I also posted this on r/RLanguage since I’m not totally sure if this is an R issue or a Docker issue or other issue, but hopefully I can at least be pointed in the right direction.
