Xprint V7.0 architecture Introduction to administering Xprint V7.0

assumes its function as the active master. The ranks of the potential masters can be defined by the order of their installation and can later be modified via specific commands.

Slave hosts are hosts that hold a complete copy of the Xprint V7.0 database but cannot become the active master host. This is useful, for example, for computers which are shut down frequently, are not very reliable, or which are still using an old Xprint V7.0 version.

A parasite host does not have a copy of the Xprint V7.0 database. It requires Xprint V7.0 to be running on a specific computer which is assigned to it as the database server, also referred to as the supporting host, if the parasite host is to access Xprint V7.0. This only makes sense if there is a permanently running database server available for such computers which exports its database via a network file system (NFS). The database must then be mounted into the local file system by the parasite host.

●Job templates (-jtp)

Job templates simplify the use of frequent print commands by allowing the options of the xpadd -jobcommand, which must normally be specified individually, to be combined in groups. These can then be specified via the job template.

Job templates can be defined, modified or deleted for the whole system by the Xprint V7.0 administrator or user-specifically by each individual user.

●Loadable resources (-lrs)

Loadable resources allow faster printing of jobs that use the same background, logo, soft font etc. They also improve job recovery. A Loadable resource must be downloaded to the printer before it can be called by a print job.

Public loadable resources can be created, modified or deleted for the whole system by the Xprint V7.0 administrator. Individual users can create, modify or delete private loadable resources, that is loadable resources that are for their use only.

●PCLs (-pcl)

PCLs (printer capability lists) are used to define what printing options a printer provides. Furthermore, the PCL contains information on how the options specified when the job is submitted can be converted to printer commands. Xprint V7.0 is supplied with a number of PCLs for the most
