Spooler Structure
The spooler on jBASE is a fairly straight-forward process. The actual
print processes are jspprint programs that pipe the stdout of a report into
whatever is specified in the SP-DEVICE command for that queue.
Typical directory structure
spooler -- default directory name for spooler
jobs -- Directory Holds "formqueue_"# directory for each
queue
formqueue_0 -- Directory Holds actual print jobs form
formqueue "0"
1 -- *nix/Windows item of print job "1"
2 -- *nix/Windows item of print
job "2"
4 -- *nix/Windows item of print
job "4"
formqueue_1 -- Directory Holds actual print jobs form
formqueue "0"
3 -- *nix/Windows item of
print job "3"
5 -- *nix/Windows item of print
job "5"
jobs]D -- Empty DICT level of jobs file
jspool_log -- jBASE hashed file. See typical items listed below
jspool_log]D -- jBASE DICT file with dictionary
defining items
Typical jspool_log file items
| DEVCONFIG*0 |
-- Holds definition of device 0 |
| DEVCONFIG*1 |
-- Holds definition of device 1 |
| NextJobNumber |
-- Holds DATE() in attribute 1 and next job number in
attribute 2 |
| DEVLOCK*0 |
-- Holds PID of jspprint program for device 0 |
| DEVLOCK*1 |
-- Holds PID of jspprint program for device 1 |
| DEVJOBS*1 |
-- Holds information on job number 1 (same format for all 5
jobs) |
| DEVFORMQUEUE*laserjet |
-- Holds number of device for queue named "laserjet" |
| DEVFORMQUEUE*lineprinter |
-- Holds number of device for queue named "lineprinter" |
| OwnerGroupSpooler |
-- Holds queue ownership information |
DICT jspool_log
The jspool_log is a standard jBASE hash file and can be LISTed and reported
on using the dictionaries in the jspool_log file.

The route of a typical print job
Print queue settings derived from SP-ASSIGN and TERM
The typical print job will begin with an
SP-ASSIGN statement and possibly
TERM statement to assign the form queue and printer
depth and width. NOTE: Assignment will default to STANDARD if no
SP-ASSIGN is executed.
SP-ASSIGN =laserjet
TERM ,,,,,,112,30
Banner / Form Width and
Depth set from jspform item
The default jspform item located in $JBCRELEASEDIR/config/jspform_deflt
will set printer width to 132 and depth to 64 regardless of the
TERM setting specified and on LINUX will specify a
banner to be used. This item is self documented and can be altered.
Be aware that this item would be overlayed if jBASE were upgraded.
SP-TYPE can be used to assign other than
this default formtype.
Translation occurs based
on jspxl item
Translation item as defined in SP-TRANSLATE
or $JBCRELEASEDIR/config/jspxl_deflt is read to determine what translations are to
take place. NOTE:
SP-TRANSLATE item
read only when printer is initialized.
The item is passed via stdout to the device specified
SP-DEVICE defines the
device/program used for printing. This is typically the local printer
program lp, but with the PROG device type any program that can read from stdin
(INPUT) can be used.
