We have a 1050c that has worked excellent until we upgraded to LDDT 2005. Now it won't receive plots from ACAD even though ACAD says it plotted with no errors. I have searched for a new driver can't find one. We are using HP's driver v4.66 still doesn't work. It plots fine from other applications. I recreated the pc3 file from the system printer in 2005 and still nothing. Got desperate used a hp750cm heidi driver, it receives now but won't recognize the wipeouts we use on some symbols because the heidi driver doesn't do rasters well. Anyone have any thoughts that might help?
