Configuring Spoolers, Queues, and Logical Printers
Creating and Configuring Logical Printers
For example, if the user submits a job specifying the document
attribute content-orientation=landscape, then the landscape
value is compared to physical printer attribute
content-orientations-supported.
• Job attributes that request a particular type of printer, such as
printer-models-requested.
HPDPS compares the values of the job attributes to the values of the
physical printer attributes of the particular printer-model.
See “Creating and Configuring Physical Printers” in Chapter 5 for
further information on physical printer configuration.
See pd_att_phy_ptr(5) and pd_att_log_prt(5) for a list of attributes for
physical and logical printers.
Job/Document Attributes Requiring Initial Value
Objects for Restriction
Many job and document attributes do not have default values. If you
want to restrict the printer capability that corresponds to a job or
document attribute that has no default value, you must create an
initial-value-document or an initial-value-job object and associate it with
the logical printer to ensure that the intended restriction is enforced.
For the document attributes that do not have default values, when the
job is actually printed, the printer device must still perform processing
that corresponds to each of the document attributes. For example, it
prints on either one side or both sides of the medium, regardless of
whether sides-supported is set. Each printer has default processing
for each document attribute.
See “Using Initial Value Objects to Ensure Restriction” later for more
information; also see “Using Logical Printers to Restrict the Use of
Printer Capabilities” later for an example configuration that uses an
initial-value-job and an initial-value-document object to enforce
restrictions imposed by logical printers.
Table 6-1 shows some document attributes, their defaults, and the
corresponding printer attributes and supported values. The plex and
sides document attributes do not have default values. If you use either
of the corresponding logical printer attributes for restriction, you must
create an initial-value-document object to provide a default value.
