# Description
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

# Typical jspool_log file items
| File item | Description |
|---|---|
| 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 that 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 that 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.
