Eduardo E. Zambrano Q.,

The problem this while themselves this printing the reports these delay
approximately 2 minutes in beginning to be printed

it could be related with the LPT timeout problem when printing from DOS on a
XP system.
Does the print job start immediately if you exit the DOS app.?

Kind regards,
Davide Guolo

Eduardo,

pause. in the two cases if the exit DOS app continuous the impression

If exiting the DOS app. your print jobs starts immediately, then the app. is
not closing the printer port at the end of the job, so it's not spooled
until Windows reaches the timeout value (or the app is closed).

The best solutions could be to fix the DOS app., but if you cannot, then try
the following:

Go to SYSTEM.INI file
in [386enh] section search [Network]
if it does not exist enter the following :

[Network]
PrintBufTime=10
[IFSMGR]
PrintBufTime=10

This should set the timeout to 10 seconds.

There is also a solution I found on the net, changing the Windows Registry.
Please note that I HAVEN'T TESTED IT and take care using RegEdit: it could
be rather dangerous.

in REGEDIT ( START->RUN-> REGEDIT )
click : Hkey_local_machine
then click : System
then click : CurrentControlSet
then click : Control
somewhere at the bottom of the control list Click: WOW
Here you should find the LPT_timeout property

You may also want to have a look at Printfil, which can enable your DOS app.
printing to any Windows printer, including USB, GDI (Windows-only) and
Virtual (like Faxmodems and PDF writers/e-mailers) with many extras, like
print preview, font selection, BMP background merging and so on.
