Spooler
-----------------------------------------------------------------------------
By : J. Vande Ginste (1993)
This program allows you to print textfiles in the background. You
start up the spooler with the command 'Spooler'. Then the spooler
will constantly watch the directory SPOOL: and as soon as a file
is copied to the directory SPOOL:, this file will be printed.
When more than one file is present in the SPOOL: directory, all
files are placed in a waitqueue and printed one by one.
The program can be in a number of states :
Idle Waiting for a file to appear in the SPOOL: directory
Printing A file is currently being printed. The filename is
displayed in the File-Display at the bottom of the
spooler window. A horizontal bar shows you how much
of the file is already printed.
Finishing Same as printing but spooler will stop as soon as
current file is printed.
Halted Printing has been stopped
Possible actions during idle state :
.------.
| FF | Give a FormFeed to the printer
`------'
Possible actions during printing state :
.------.
| HALT | Stop as soon as current file is printed
`------'
.------.
| GO | Continue printing after being halted
`------'
.------.
| SKIP | Stop printing of current file and proceed with
`------' the next one
Possible actions during halted state
When in the halted state, you can select a file from the
spoolerlist. This file will appear just beneath the spoolerlist.
.-------.
| DEL | Remove selected file from the spoolerlist and delete
`-------' it from the SPOOL: directory
.-------.
| FIRST | Place selected file at the top of the spoolerlist
`-------'
.-------.
| LAST | Place selected file at the bottom of the spoolerlist
`-------'
.-------.
| CLR | Clear the spoolerlist. A file must not be selected.
`-------'
How to set up an enviremont in which the spooler can run.
A number of things have to be done before the spooler can work.
1. Add the following lines to your user-startup :
makedir RAM:Spool
assign SPOOL: RAM:Spool
run > NIL: spooler # send files to the screen
run > NIL: spooler PRT: # send files to the printer
Remark : don't use redirection for spooler.
2. Create a script called 'spool' (optional)
.KEY file/a
copy <file> to SPOOL:
Make sure the s-flag is set for the script 'spool':
protect s:spool +s
How to end the spooler :
- Give the command 'Spooler remove'
or
- Click on the close gadget of the spooler window
Remarks :
- Spooler will not print .info files, these are just deleted
from the SPOOL: directory. This means that you can drag icons
representing textfiles into the SPOOL: directory.
- As soon as Spooler finds nonprintable characters in the
file, the printing will be aborted.
I hope you like the program.
