We have a print server running system 10.5 on Apple talk due to an older imagesetter. When I print from a partition on the iMac running 10.6.8 I can connect and print. When I try to print from the partition running Yosemite because of Adobe CC programs it will not recognize the printers on Apple Talk. Both 10.6 and 10.10 do not use Apple Talk, so why does the 10.6 recognize it. Is there a way around this to allow Yosemite to print to an Apple Talk server? Thanks.
