Remember to select your Operating System (OS). I'm guessing you are using Windows 7.

i need the drivers of the printers hp 3550 deskjet

Here is the driver download page for your system (click here), just select windows version and start download.
You will have to run the file after downloading, it will start a setup wizard, keep printer unplugged from PC usb until required from install wizard.

connect to the hp website and download drivers for your printer(hp deskjet 3745) then run the set up of the downloaded file.

I hope this will go a long way in helping you.

Rizla has sent you to the right place. All the printer manufacturers generally have the drivers available for free download in the "Support" section of their website.
