I am not sure I am in the right forum for this posting, but will start here, anyway.

Using XP and an HP printer.

Whenever I boot up, I get the error message that says file hpzrp305.dll is missing. It does not yet seem to interfere with my using my computer. Though I have not used the printer, because of an apparent color cartridge issue.

I went to several sites which want to sell me registry scanners. I went to one site which promised to allow me to download the missing file, but the site did not look trustworthy. Searched here, but apparently this issue has not been brought to your attention.

Point me in the right direction. I would appreciate it.
