Thanks for your suggestions, but they did not work.
Meanwhile, I continued my investigation and found that
1) At my office, where I have the same Windows XP, everything works fine.
That is, I have no problem printing to file.
2) At home, I discovered that there is something wrong with the
port FILE:
When on "Printers and Faxes", when I click properties and then select "FILE:" as "port", if I click on "Configure Port", I get a message saying "The Fax Talk
driver is automatically installed when you install the Fax Talk software.
Current Fax Talk port FAX2: mapped to COM2:."
I uninstalled, using "Add and Remove software" from the Control Panel, the
FaxTalk Communicator. But it did not work.
I also notice that the port COM2: is not listed in the lists of available ports.
Please advise.
