If this postscript is failing to print, then you will need to find out how the postscript is being created in order that you can intervene. Non-postscript jobs are dealt with by the informatics print filtering system, meaning essentially that the file type of the job is detected and a converter is then used to convert the job into postscript prior to it being printed (e.g. PDF documents are converted to postscript using the acroread -toPostscript command). The print logs will give details of the command used to produce the postscript. Printing from Macs or PCs on the other hand will most likely result in the postscript being generated before it is submitted to an Informatics print server (i.e. by the Mac or PC). This is a very common source of nasty postscript. If you see from the logs (using lpq -llll or lpq -L) that a job of yours is failing t
