Overview
--------
One of the things Workbench 2.0 (and 3.0) is still missing is a printer
spooler.
PrintManager is just that. There are some other programs that try to
implement a spooler on the Amiga, but:
· PrintManager is a system wedge, so it will work with every program, not
just ones explicitly written to take advantage of it;
· The wedge is installed at parallel or serial device level, so PrintManager
will really work with EVERY program: no matter if it uses PRT: or directly
the printer device, no matter if it's printing text or graphics. Even
programs that use directly PAR: or SER: can be cached using the DEVICE
ToolType.
· Only printer device calls are cached, so modem and net users will not
experiment performance loss.
· PrintManager has a nice, font sensitive graphic user interface (GUI) and
supports localization under Workbench 2.1 or later.
· You can print files directly from PrintManager, using either the AppIcon,
or the AppWindow, or a menu command.
Under Kickstart 2.x only text files may be printed; under Kickstart 3.x
datatypes.library is used so you can print anything which is recognized by
MultiView.
· The printer-specific raw data can be saved to a file. That file may be
printed at a later time via PrintManager itself, or brought to another
computer (since it contains raw data, you just have to send it unchanged
to the printer). For example, you may prepare an article at home and use
the expensive laser printer at office to print it.
· After a system crash or reset, unfinished printings are automatically
recovered. This feature may also be used to prepare raw data and print it
at a later time.
· A Form Feed may be automatically inserted between printings.
Requirements
------------
· OS 2.04 or later
· Hard disk is not required but strongly recommended
· Printer ;-)
Installation
------------
Copy spool.device in DEVS:.
The spooler is actually activated by running PrintManager. Some parameters
may be changed via icon ToolTypes. Recognized ToolTypes are:
CX_POPUP default: YES
This one tells if the program window should be opened when it is run for
the first time. If you drag PrintManager's icon in the WBStartup drawer
to activate it automatically, you should set this ToolType to NO.
CX_POPKEY default: control alt p
This is the "hot key", the input sequence which opens the window if it is
closed, or brings it to the front if it is already open. Refer to the
Amiga User Manual for a complete specification of the recognized keywords.
CX_PRIORITY default: 0
The priority of the commodity handler used for the hot key. You will not
need to change this.
SPOOLDRAWER default: T:spool
The directory where temporary files should be stored. You should change it
to somewhere in your hard disk, since on a standard machine T: is assigned
to RAM:T. Temporary files may be quite large (some megabytes if you are
printing graphic in high density), and you could run out of memory very
quickly otherwise.
If the directory specified doesn't exist, it will be created.
PRINTDRAWER
The name of the directory where the "Print..." file requester should be
positioned the first time it is invoked.
SAVEDRAWER
The name of the directory where the "Save As..." file requester should be
positioned the first time it is invoked.
PAUSED default: NO
This specifies the initial state of « Next Job ». See later for details.
APPICON default: ACTIVE
PrintManager can put an icon on the Workbench screen. Double clicking it
will act like pressing the "hot key"; dragging files on it will cause
them to be added to the print queue.
There are three valid keywords for this ToolType:
ALWAYS - Show the icon when the program is started, remove it when
quitting.
NEVER - Never show the icon.
ACTIVE - Show the icon only if the print queue is not empty and the window
is not open. This feature will help to remember if there are recovered
jobs after a reset.
ICONX
ICONY
These two specify the position on the Workbench screen where to put the
icon. If you don't specify _both_ of them, Workbench will place it by
itself.
PUBSCREEN
The name of the public screen where to open the window. May be very useful
if used together with the program "FrontPublicScreen" included in this
archive.
DEVICE
UNIT
By default, PrintManager will automatically detect if the printer
configured in Preferences is parallel or serial, and will intercept calls
to the appropriate device only if they are made by printer.device.
This means that PrintManager will not interfere with, for example, a
scanner connected via a switch to the same port of the printer.
Unfortunately, it also means that only programs using printer.device or
PRT: will benefit from the spooler; programs using parallel.device or PAR:
will not.
Providing a device name (and an optional unit number) will cause ALL and
ONLY the calls to that device to be cached. For example, for a parallel
printer use:
DEVICE=parallel.device
CREATEICONS
Specifies if files created with the "Jobs/Save As..." command should have
an icon or not. This is the same as the menu Settings/Create Icons?
AUTOFORMFEED
If this is set to YES, a Form Feed will be automatically sent to printer
after each job. This is the same as the menu Settings/Auto Form Feed?
Using the GUI
-------------
GUI usage should be fairly intuitive; clicking on a job makes it the
"current" one, and allows you to perform some operations on it.
You may pause/restart the job using the Active/Paused cycle button, or
remove it from the list with the Remove button. You can sort the list using
the Up and Down buttons. A job being printed cannot be moved from the top of
the list. Jobs brought to the top of the list are automatically paused to
prevent accidental activation.
Above the print queue are displayed the name of the job currently printed
and a progress bar showing the percentage of data sent to the printer.
Note: the progress bar doesn't appear until the program which is printing
completes its work.
There is a special entry in the list, named "« Next Job »". It represents
the position where the next job you start will be placed. The new job will
also inherit the setting of the Active/Paused button. This means that if you
set « Next Job » to Paused, nothing will be printed until you explicitly
start it. The initial setting of the Active/Paused button may be changed
using the PAUSED ToolType.
When started, PrintManager will look in the SPOOLDRAWER you specified and see
if there are jobs left from previous sessions. If it finds some, they will be
automatically inserted AFTER « Next Job ». This way, you can continue to use
the printer without taking care of old jobs; when you want to restart one of
them, you just have to open the GUI, bring the job to the top of the list,
and unpause it. To restart them all, bring « Next Job » to the bottom of the
list and unpause the first job.
Printing from inside PrintManager
---------------------------------
Files may be printed directly from inside PrintManager. This can be done in
three ways:
· Dragging icons on the AppIcon (that is the icon in the Workbench window,
NOT the program icon). The status of the AppIcon may be changed using the
APPICON ToolType.
· Dragging icons on PrintManager's window.
· Using the Project/Print... menu item.
Under Kickstart 2.0, only text files may be printed. Under Kickstart 3.0,
datatypes.library is used, so you can print anything that is recognized by
MultiView.
Moreover, raw data saved with Jobs/Save As... may be recovered. This feature
may be useful, for example, to print multiple copies of a document.
NOTE: Raw data files are recognized by their comment, which must be
"Raw Printer Data". When you save them using Save As... the comment is set
automatically. Make sure not to modify it.
Menus
-----
Project/About
Self explanatory.
Project/Print...
Brings up a file requester allowing you to select one or more files to
print. This is the same as dragging icons over the AppIcon or the
AppWindow.
The initial drawer displayed by the file requester may be changed with the
PRINTDRAWER ToolType.
Project/Hide
Closes the window, but leaves PrintManager resident in memory.
Project/Quit
Terminates PrintManager. You cannot quit if the print queue is not empty.
Jobs/Save As...
This allows you to save a job as printer specific raw data. The file
created may be sent directly to the printer, either via PrintManager, or
a device like PAR:, or even on a different computer.
This operation cannot be performed on jobs which have "n/a" in the Size
column.
Since the copy of the file happens asynchronously, it is a good idea to
pause printing before saving. Otherwise, the operation will take much
longer, due to contemporary accesses to the hard disk by two different
tasks (the one which copies the file, and the one which prints).
IMPORTANT NOTE: the saved files have a "Raw Printer Data" comment
associated. That is the only way PrintManager has to recognize such files
from the other files you try to print. If you remove or modify the
comment, the file will not be printed correctly.
The initial drawer displayed by the file requester may be changed with the
SAVEDRAWER ToolType.
Jobs/Remove All
Removes all the jobs from the print queue.
Options/Create Icons?
Specifies if files created with the "Jobs/Save As..." command should have
an icon or not.
The initial setting of this item may be changed using the CREATEICONS
ToolType.
Options/Auto Form Feed?
If this item is checked, a Form Feed will be automatically sent to printer
after each job.
The initial setting of this item may be changed using the AUTOFORMFEED
ToolType.
Limitations
-----------
Currently, only one device at a time may be spooled. You cannot work around
this limitation running multiple copies of PrintManager, because there can
be only one copy running at a time.
However, if you are not using the DEVICE ToolType, the spooler will
automatically switch from parallel to serial if you change the Preferences
settings. The print queue must be empty for the change to take effect.
Removing this limitation is not a trivial task; an additional difficulty is
that I don't have two printers to test it. Since most users are in the same
situation, I've decided to leave it as it is, for now. Whether I improve it
or not will depend on many factors, not last how many shareware
contributions I'll receive.
