Multiple printer recommendation

I have a customer in the graphics business. He has 2 Epson 1280 Stylus printers 1 is connected paralell port directly, 1 is usb via 2port dlink server which also has a Xante laser printer connected to it. His compter is a windows 98SE system 512mb sdram 80 gig hd (Win98 because of some software compatability issues). He wants to add 2 more Epson 1280 printers and be able to monitor all ink cartridges. Should I recommend a new computer as a print server just to manage/monitor all printers? Or do I recommend another network printserver? Any help is greatly appreciated.
