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 -job command, 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
