Think about it. There's nothing in one installation of ID to affect another installation. So it is at the router if wireless, the print server itself, etc. It sounds like whichever it is, is not processing an end of file marker or otherwise truly clearing the print job. Now, from reports here, printing direct from ID can be an iffy proposition. I myself don't have issues to my networked Xerox printers. But once in a while there are reports here.
If you create a PDF and print from it, can another station print a PDF? If so, there is something about how ID is sending data that the hub/print server is not processing from ID. If PDFs also don't print, call Konica and hammer on them more.
I actually have created a .pdf and had others print it (a file I create in ID and export to pdf). What ends up happening is if I try to print the pdf people after me get blanks. However if someone else prints it there is no issue. I may have left out an important point I'm the only mac that uses the printer, everyone else uses pc (and I don't know if that's an issue). I only have a postscript driver available (which is good) but i don't know what everyone else is using. I want to say in all of this i heard they have a PCL driver.
As far as the router, I'm hardwired into the network so there is no router. Konica and our IT have checked the network and ruled out that possibility (and I don't really know what that means)
But you are reaffirming the fact it is the printer and they need to fix it. And the fact that a document printed with only cyan is printed with all four colors to give me some weird off color makes me think the disconnect is between Adobe and the printer. But still so weird about the blanks.
Thanks for the input
