Printer Name In Devices And Printer Keeps Changing Every Few Seconds?

I have an MX850 and an MX870 printer both connected to my LAN.I also use an application called CD Label Print. When I started that program I noticed that there were 3 MX850 printers listed, the original and a (Copy 1) and (Copy 2).So I went to devices and printers and saw there was a MX850 and a MX850 (Copy 2). No (Copy 1). So I removed the (Copy 2) printer and fax.I went back to CD Label print and saw that it still said MX850 and MX850 (Copy 1). Went back to devices and printers and sure enough, MX850 was gone and MX850 (Copy 1) was present. So I pressed F5. It changed to MX850. Press F5 again, it changed back to MX850 (Copy 1).It changes non-stop. It alternates betweem the two settings every time I press F5.I've tried uninstall re-install. I've also contacted Canon support who are dumbfounded. I also had to manually remove the registry entries and start menu entries because the canon uninstaller doesn't so it.I cannot use CD Label print. Each time I try to print a label it insists on asking where to save the file, rather than printing it.
