print server and photo inkjet

I am using D-Link print server with Epson R200. Basically it works but
when printing photos which means BIG files, the printing process might
stop near the end of the job. My speculation is printer buffer overflow
and because it's not connected via USB so the printer can't tell the
driver to wait for the buffer to clear. Is there a way to make sharing a
photo inkjet via print server possible? I think there are print server
with buffer built in but I am not ready to spend money for that. Thanks.
