Not really. If you want to print K7 then QTR is it. (There is one other RIP that does K7, but it's only for older, very large printers.)
If you want to print borderless, then the main option that I know of is the Epson driver, which would mean standard inks and not K7, and either selecting ABW in the driver or printing B&W using a colour ICC. I imagine other RIPs also print borderless, e.g. Mirage, Imageprint, Colorburst, Printfab, but again we're talking standard inks and not K7.
