I am attempting to add an HP psc 700 series printer on my Windows XP system. I receive an error message that the file dot4usb.sys is not found, and setup will not complete successfully without it. So far, I haven't been able to find out anything about this file.

I really need this printer to print my tax return, and will greatly appreciate your help! Thanks.

Thiere is a similar issue beneath although on a different HP system and HP printer. Maybe it's worth to check anyway

HP Compaq Thin Client t5700 systems display the following error message during setup of an HP LJ1200 printer

ERROR Dot4usb.sys and Dot4prt.sys missing

The issue occurs because the files have been installed in a location other than that indicated in the registry.

Information in this document applies to HP Compaq Thin Client t5700 operating in a Microsoft Windows XP Embedded environment.
Users can resolve the problem by moving the files to the correct location.  The files (Dot4usb.sys and Dot4prt.sys) are located in the C:\Windows\i386 folder and should be moved to the C:\Windows\system32 folder
