What is TurboPrint ?
TurboPrint was designed to overcome the printing limitations dictated by
the Amiga's operating system and to use the capabilities of your printer
to their full extent. Although the Amiga as a graphics computer is capable
of producing and displaying brilliant, colourful and attractive graphics,
its printer interface often leaves much to be desired when it comes to
graphics printing. With TurboPrint, the graphics output will match the
quality of your screen display, as it features special graphics algorithms
normally only used for high-end production in the professional printing
industry.
TurboPrint is currently the only printer driver system for the Amiga
which will allow you to print graphics in all 16 million colours
available through the AGA graphics chip set via the normal Workbench printer
interface. Only Turbo Print offers a complete replacement of the printer.device,
removing the limitation of 4096 colours or 16 grey scales, respectively.
With TurboPrint's Graphics Print Manager you don't need the AGA
graphics chip set or a third party display board to print 24 bit-graphics
in photographic quality. This TurboPrint add-on enables you to print pictures
directly from floppy or hard disk in maximum resolution and with the lowest
memory consumption possible. It even supports PC graphics standards like
JPEG and PCX. Apart from the above, TurboPrint allows for numerous settings
to manipulate the printout, like precise size control, perfect colour settings,
powerful contrast and brightness correction, smoothing, different dithering
patterns, and many, many more. When developing TurboPrint, we especially
focused on the combination of high speed and low memory requirements.
To achieve this, the main program was written entirely in 68k-Assembler,
the fastest and most efficient programming language available for the Amiga.
Because it replaces the original printer interface of the Amiga Workbench,
all text and graphics output sent to the Workbench interface will be redirected
through the TurboPrint system. This secures highest compatibility
and flawless operation with almost every program available today. To help
you control its powerful features, TurboPrint comes with a special preferences
editor called TurboPrefs. TurboPrefs may also be installed as a resident
program waiting in the background, so that it can be immediately activated
at the click of a button. Great care has been taken to make TurboPrint
as easy to use as possible. Although having all features you could possibly
expect (and more), the program does not confuse the user with lots of settings
not really required to produce a great printout.
Additional Features of Turboprint
One of the prime design goals, apart from delivering extraordinary printing
quality and speed, was to make printing simpler. TurboPrint allows you
e.g. to produce a hard copy of the current screen or to save screens
as IFF pictures on disk, which can then be further manipulated with a paint
program of your choice. Even third party graphics boards are supported.
TurboPrint even offers a poster function to print oversized pictures
on a predefined number of sheets, which can then be assembled to create
large posters.
TurboPrint Professional
The successful TurboPrint is now available in a heavily improved version.
It is not only easier to use: the new "intelligent" printer drivers deliver
unmatched print quality, even without requiring individual user-defined
settings. The "True-Match" colour correction system enables TurboPrint
to correct each colour separately from the others, eliminating printing
errors (like blue being printed as violet) before they happen. Thanks to
newly developed algorithms and 100% optimised processor code, TurboPrint
works out these complicated corrections at a speed never seen on the Amiga
before. Although easy to use, the various configuration possibilities have
not been sacrificed. In addition to the
True-Match colour correction,
the user still can individually configure factors like brightness, contrast,
gamma value and various colour-related values. Beyond that, TurboPrint
now also provides support for individual printer models. For most of the
printers available, TurboPrefs contains a separate menu page with printer-specific
preferences. The Graphics Publisher features a special layout
mode, which allows for easy selection of printout size and position with
the mouse. In addition to that, a 256 colour dithering facility (previously:
16) produces a greatly improved screen display in combination with the
AGA graphics chip set. With third party graphics boards and CyberGraphX,
you can even get a 24 bit "TrueColour" preview! The graphics publisher
gives you the possibility to preview several preference settings, e.g.
different brightness gradients, directly on-screen. In addition, TurboPrint
now supports more graphics formats than before, e.g. JPEG, BMP, PCX and
PhotoCD.
Developer Information
Turboprint includes a 24bit printer.device and it has become the
standard for 24bit printing. If you are a software developer and want
to upgrade your application from 12 to 24bit, please download our developer
information. You will see that it requires just a few lines of code to
get real high-quality 24bit output. This 24 bit interface has been included
in Turboprint Professional since version 3 which was released in 1995,
so implementing 24bit printing using the Turboprint standard will benefit
most Amiga users.
