Submitting print jobs
Job attributes
Users may submit print jobs using an LP client programme such as lpr (BSD style) or lp (System
V style).
The user can influence the way a job is printed using specific command line options with the lpr
or lp command. Available command line options can differ from host to host as each host can
have a specific implementation. Not all command line options are meaningful for each printer.
Received jobs are stored in the printer’s spool queue. The data files in the lpd job are processed
one by one by the PDL interpreter. All print jobs are stored in the same printer queue,
independent of the LPD queue name the user has specified.
The received job attributes (Copies, Username, Jobname, Hostname) are stored with the jobs in
the printer queue. This ensures that queue viewing and job removal (which need the username,
client and hostname) will work as expected.
Job attributes can be part of the LPD protocol, the Job Ticket and can be embedded in the PDL
data. For some attributes, this can lead to conflicts. This section describes how they are solved.
#copies
The number of copies can be specified through the LPD protocol. If its value is larger than 9999, it
is ignored and 9999 is used instead. The number of copies can be also specified in the Ticket or
the PDL data.
If the number of copies specified in the LPR is not one, then this value is used as number of
copies. If the number of copies is one, it will be considered to be unknown/undefined. So that
when the request is created, a choice can be made between the Ticket or PDL number of copies
and the LPD protocol #copies.
This situation occurs when:
• The user didn’t specify a #copies on lpr’s command line,
• The user specified a #copies 1 on lpr’s command line.
Username and Hostname
The username is used to describe the jobs in the 'Waiting jobs queue' and the 'Scheduled jobs
queue'. The hostname is used in the job identification for lprm. These two attributes can be
provided by LPD, the Ticket and the PDL. When username and hostname are defined in the PDL
data, they are ignored.
Jobname
The jobname allows the user to identify his/her jobs. This attribute can come from LPD, PDL or
the Ticket.
In the Controller (lpq is excepting), the Jobname attached to each created request will be:
• Ticket JOBNAME if a ticket is provided
• Name of the original data file
On the contrary, by lpq the jobname returned by the device is the protocol filename at least for
the LPD jobs, even if the ticket holds a different jobname. Other Jobname attributes coming from
LPD or PDL are ignored.
