Officejet 5600 series printer driver

SOURCE: I lost my starter CD

Thank you contacting FixYa with your printer inquiry.
You will be able to obtain a replacement CD by contacting HP Support and Drivers through either of the following links:
http://www8.hp.com/us/en/support-drivers.html
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=3635378&lc=en&cc=us&dlc=en&lang=en&cc=us
There are three models so you can select yours from the drop down, then choose your operating system and follow the steps for ordering your replacement CD.
*Note - If your concerns are Drivers, most of HP's drivers are included in Microsoft's current Operating Systems and will self install.
Hope this helps helps. Please add to the comments if you have additional questions. Keep us updated and remember to rate this answer.
