Your programs aren't working right seems the most likely explanation. Can you print to it using generic Linux postscript drivers?

Right....so you're saying the printer and standard Linux drivers work fine, but your software doesn't. Since this is your software, that you wrote, with a custom PPD and backend, it's up to you to fix it. Hard for anyone else to diagnose a problem, for a "vendor specific printer", with a custom PPD and USB backend, when none of us here have ANY of those things.
