Glossary
Raw mode
When a print job is spooled in in raw mode, Xprint V7.0 sends this file to the
specified printer without any formatting or processing by a filter.
Recovery rule
Recovery rules are used to define the error recovery procedure in the case
of specific printer conditions.
SCSI driver
The SCSI peripheral driver communicates with the SCSI host adapter server
instead of directly with the hardware. It contains entry-point routines to pass
user-level request to open and close the device or to read and write data.
The SCSI peripheral driver populates a request structure with this infor-
mation, then passes the information to the SCSI host adapter driver. The
host adapter driver handles the direct communication with the hardware.
Server
Servers are the Xprint V7.0 objects which administer incoming print jobs and
are responsible for scheduling them. Every server manages its own print
queue, which contains all the print jobs for the printers whose supervisors the
server controls.
Slave host
A slave host is a host which holds a complete copy of the Xprint V7.0 database
but cannot become active master host itself.
Slow filter
This is a program enhancing the functionality of Xprint V7.0. Slow filters are
executed in parallel to the spooling process, i.e. after job submission and
before printing. They convert data or allow special print modes such as
printing in columns or in landscape mode.
