I do not have PD4 set to auto launch on login and I have nothing connected to the USB port. These printers are network printers using either Bonjour or specific IP addresses. To be clear, the printers are missing from my host computer before I run PD4 or any other application. When I launch the OS-X Printer Setup Utility, no printers are listed. Attempting to add a printer results in an error that the service is not available. Launching the Network control panel in OS-X results in an error that the service is controlled by another application.
I then re-booted into single user mode, ran fsck, re-booted into OS-X and ran Disk Utility in OS-X to repair permissions. Launched OS-X Printer Setup Utility and the printers are now populated in the printer window and function normally.
Since my first post, I enabled Printer Sharing in the OS-X Sharing control panel and ensured Printer Sharing is enabled in the OS-X firewall. I also disabled firewall in the guest OS. Since then, the error has not yet recurred.
