SLOW PRINTING WITH SUPERSPOOL
|
|||
|
|
AND CERTAIN SOFTWARE APPLICATION
|
|||
|
|
|
|||
|
|
|
|||
|
|
Certain software application, like Lotus 1-2-3, sends control
|
|||
|
|
characters to LPT1 upon initialization. These control characters
|
|||
|
|
interfere with the automatic timing calibration of SuperSpool.
|
|||
|
|
This could result in slow character printing and or a delay at
|
|||
|
|
the end of each printed line.
|
|||
|
|
|
|||
|
|
This condition can be remedied by sending a burst of twenty-five
|
|||
|
|
characters (blank spaces, in this instance, may be the best
|
|||
|
|
characters to use) to LPT1 after invoking SuperSpool but prior to
|
|||
|
|
initializing the software application.
|
|||
|
|
|
|||
|
|
The following procedure outlines the steps in creating a data
|
|||
|
|
file named DUMMY.DAT and installing it in the AUTOEXEC.BAT file.
|
|||
|
|
This should eliminate the slow character printing and/or
|
|||
|
|
hesitation after each printed line.
|
|||
|
|
|
|||
|
|
Step #1: First we need to create a data file named DUMMY.DAT
|
|||
|
|
consisting of 25 blank spaces.
|
|||
|
|
|
|||
|
|
COPY CON:DUMMY.DAT <CR>
|
|||
|
|
Press space bar 25 times <CR>
|
|||
|
|
Press F6
|
|||
|
|
|
|||
|
|
(Response) ^ Z
|
|||
|
|
|
|||
|
|
(Response) 1 File(s) copied
|
|||
|
|
|
|||
|
|
1 File(s) copied means you have successfully created
|
|||
|
|
DUMMY.DAT.
|
|||
|
|
|
|||
|
|
Step #2: Now that DUMMY.DAT has been created, the next step
|
|||
|
|
is to assign it to LPT1. This sends a burst of 25
|
|||
|
|
characters to LPT1.
|
|||
|
|
|
|||
|
|
COPY DUMMY.DAT LPT1: <CR>
|
|||
|
|
|
|||
|
|
Step #3: Once Step #2 has been executed, the command "COPY
|
|||
|
|
DUMMY.DAT LPT1:" can be installed in the
|
|||
|
|
AUTOEXEC.BAT file. This command should be installed
|
|||
|
|
after SuperSpool but prior to initializing the
|
|||
|
|
software application.
|
|||
|
|
|
|||
|
|
The example below is the simplest form of the
|
|||
|
|
AUTOEXEC.BAT file:
|
|||
|
|
|
|||
|
|
|
|||
|
|
BEFORE AFTER
|
|||
|
|
|
|||
|
|
1st Line --> ASTCLOCK 1st Line ASTCLOCK
|
|||
|
|
2nd Line --> SUPERSPOOL LPT1: 2nd Line SUPERSPOOL LPT1:
|
|||
|
|
3rd Line --> Software Application 3rd Line COPY DUMMY.DAT LPT1:
|
|||
|
|
4th Line Software Application
|
|||
|
|
|
|||
|
|
Step #4: Now all that is required is to reboot the system and
|
|||
|
|
you are ready to go.
