The more I think about it, the more clear the problems become.
1. Network Printer
This printer usually prints fine. We have 2 networks. It is on one and I'm on another. There is a computer that acts as a spooler, connected to both networks. It shares the network printer from one network to another. The problem with this printer is that the jobs remain visually in the queue. They print, but my computer says it's still processing. Otherwise, I think this printer is working. Konica Minolta C360 Series PS-P
2. Shared Printer
This printer either works once or not at all. It is connected directly to a workstation, which then shares it on the network. The first time I printed to it yesterday, it printed (a LibreOffice document). I then sent something from Firefox and it didn't print. Afterwards it wouldn't print anything. Nothing was in the queue for my computer or on the host computer. Afterwards I also couldn't even print from the host computer. HP LaserJet 1000
