FOR THOSE WHO HAVE THEIR LASERJET'S CONNECTED TO THE PARALLEL PORT.
*******************************************************************
In version 5.03 of LSU, there was a "bug" in the error trapping
routine -- the routine that warns you if the printer is not turned on,
or is offline. Basically what happens if the printer is not connected
or is not ready, LSU (through DOS) tries several times to get through,
and after a certain amount of time, if it fails, an error code is
returned.
This procedure, unfortunately, is very inconsistent from machine to
machine, from DOS version to DOS version, from BIOS to BIOS. As a
result, the "time out delay", that is the length of time LSU will try
to reach the printer before considering it offline, which worked on my
machine when I wrote the program may not be long enough on your
machine. If the TimeOut delay is too short you can get false "Printer
Not Ready" errors when you are printing a file of any length. This is
because the printer buffer is "busy", LSU (through your BIOS/DOS
combination) is getting the message that the printer isn't there at
all, and LSU tells you, incorrectly, that the printer is not online.
This version of LSU allows you to set the TimeOut delay. The default
is 3; this should work on most machines. If, however you are getting
false Printer Not Ready errors, then you might try incrementing this
value by 1 then printing the same file again. The range of Printer
delay values is 0 - 9. You increment these values by simply selecting
the Printer delay option under the Options menu. Do this either by
pressing the letter "P", or by highlighting "Printer delay" and pressing
the Enter key. Each time you select the option the value increments
by one, then from 9 to 0.
The Printer delay value is set under the Options Menu. When you Save
defaults, the current value is saved to disk (remember, in order to
save defaults two conditions must be met: the program must retain the
name LSU.COM and 2) you must be logged onto the same directory as
LSU.COM.
***************************************************************************
SAVING THE CURRENT RETURN ADDRESS AS THE DEFAULT.
***************************************************
LSU comes with my address in the return address slot. In version
5.03, if you typed in your address, then saved defaults, your address
became the default return address when you pressed Envelope.New.
However, (due to sloppy coding on my part), it was non-obvious how to
clear out the return address altogether and save an empty envelope as
the default... (you had to enter a space...).
Now, this whole thing has been changed.
From the envelope editting screen, the current return address is saved
as the default when you press F10. Like all other saving to disk,
this requires the same two conditions outlined above.
