AST TURBOLASER LASER PRINTER CONTROLLER IDENTIFICATION
|
|
|
|
|
|
PURPOSE
|
|
|
|
1. To identify the various configurations of the Laser
|
|
Printer Controller (LPC) printed circuit boards used
|
|
with the different models of AST's TURBOLASER Printers.
|
|
|
|
2. To assist users in identifying the correct software to
|
|
be used with corresponding LPC's.
|
|
|
|
GENERAL:
|
|
|
|
AST RESEARCH markets several models of the Turbolaser
|
|
Printer identified as follows:
|
|
|
|
TURBOLASER (Also referred to as /XL)
|
|
TURBOLASER/EL (Entry Level)
|
|
TURBOLASER/PS (PostScript)
|
|
|
|
All of these printers can be upgraded with various
|
|
options to increase memory size, add the PostScript
|
|
option, and additional soft fonts.
|
|
|
|
Each model uses unique software and fonts to control
|
|
printer operation. Users should not use software or
|
|
fonts unless designed for that particular printer.
|
|
|
|
-Do not use /EL software on /XL printers.
|
|
-Do not use /XL software on /EL printers.
|
|
|
|
Please refer to Page 2 for assistance in identifying the
|
|
various configurations of the LPC. Although each part can be
|
|
identified by a unique part number, once assembled (adding a
|
|
Memory Pak or changing the PAL chip), the true identity must
|
|
be determined by visual observation.
|
|
|
|
LPC's configured for /EL Printers, will have a PAL chip at
|
|
location U51, AST part number 107101-293. Upgrades are
|
|
available from AST Research to enhance the capabilities of
|
|
the /EL printer.
