I feel like sacrifices imply a connection with the otherworldly that don't fit with the Internet theme. No matter how cryptic you can make a web project, the Internet as a whole is deeply linked to humans that create and expand it.
Now, printers on the other hand... they work when they feel like it, come up with errors that make no sense, and each specimen of each models requires a different prayer for them to actually do their job.
I had a printer that wouldn't print if it detected a black ink cartridge. It just didn't want it. Black had to be made by combining the rest of the color cartridges. My husband's printer sometimes just disappears. It doesn't connect to any computer, phone or laptop no matter if wireless or with cable. Readjusts itself after 20 minutes. All we have to do to "fix" the problem is wait for them to finish whatever tantrum they have.
And paper jams? Obvious sacrificies. Paper is expensive, having it ruined between the printer rolls is definitely a waste of material, and it originally came from vegetal fibre, so it was once alive. A blood sacrifice through and through!
