Printers :: loading other drivers

My Lexmark Z11 works under Ubuntu using the lxm3200-tweaked driver, so I want to add it to dsl-1.0. I tried copying the PPD from linuxprinting.org to /usr/bin, but it was not made available to apsfilter. I tried the same with the cZ11 drivers but got the same results as "Topic: getting a lexmark z11 to work, lexmark z11 printer", i.e. "ERROR: addition filter 'cZ11' was not found"...

/usr/bin seems to have '.xml files, so I expect I'm missing a step. Any ideas ?

Thanks !
