Re: LPT1 missing port

Thanks for the information Alan.

I have finally got around to looking at the registry in Windows XP and this
is what I found.

In "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Monitors\Local
Port", there are 2 entries as follows :

Filename=(by default); Type=REG_SZ; Data=(undefined value)
Filename=Driver; Type=REG_SZ; Data=localspl.dll

Note: I have a French version of XP and so I have translated some words
(data, undefined value) so they may be different from the English version of
XP.

In the other registry that you gave
(HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Ports), there
is a list of COM and LPT ports including LPT1 so this seems ok.

Is the problem possibly due to the default file in the
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Monitors\Local Port
registry?

Should I delete this file and leave only the "Driver" file?

This sounds like another application removed or replaced the spooler binary
registry setting for local ports.

I have seen issues when the LPT ports are no longer listed by the spooler
because another application replaced the registry entry of the dll
controlling where to look in the registry for the port list.
reg key is here:
Local Port should point to this binary
HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors\Local Port\Driver
reg_sz = localspl.dll


The Port list that the spooler reads at startup is here:
HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Ports

LPT ports should be listed here

Hello,
When I try to print a document from any programme (Word, Works, notepad,
etc), I get a message to say that the file hasn't been sent to the printer
i.e. the computer can't sens the data to the printer.

The printer (Epson stylus color 440) works fine on my other computer
running
XP so it isn't the problem.

I did not install or change anything on the computer when the problem
started but I have been having problems with a spyware that I couldn't
remove
and that may have modified the registry (Winantivirus 2006 - these people
should be jailed). I have seen in other messages that a modified registry
may
be the problem. However, I am reluctant to use regedit without advice
since I
am not an expert with XP (or any other programme infact).

I checked the ports in system manager and there is no LPT1 port shown
although the microsoft standard driver still seems to be in the
windows/system32 directory.

Is there a way of making XP re-install the driver that is not too
complicated or risky?
The help desk of the computer manufacturer has told me to re-install
Window
XP but is there an easier way? If I do re-install XP, do I risk losing any
of
my data files on the hard disk?

Thanks for any help.
