I take it that all of these items are missing from Browserlinux?I've installed CUPS, ghostscript, the libtif package, and foomatic-rip (which is required by my driver).
The various parts of the CUPS printing chain need to be installed correctly as a group or the process fails. I would suggest that you get a standard Puppy like 4.3.1 and upgrade CUPS from here.
Once you have your printer working in that environment, you can go back to Browserlinux and try again.
