My firm has begun using Vectorworks more intensively, and is beginning to have problems plotting on our HP 1055CM. Typically, a drawing will appear to spool successfully to the plotter, but then the plotter will spit out yards of blank paper with a few scant lines of gibberish on it.
We suspect memory problems, so we tried selecting the Raster option to no avail. We have printed large photoshop files and that doesn't seem to cause a problem. We are using PCs running XP, and use either the HP DesignJet 1055CM by HP driver, or the HP 1055CM PS3 driver.
