Note: HPLIP is an open source solution for most HP printers and all-in-ones. Some printers, however, are unsupported. The reasons for this may include issues with intellectual property, technical issues, or limited production numbers. Be advised that printers that appear on the unsupported list may never be supported by HPLIP.

All information provided is believed to be accurate but is not guaranteed.
Notes:
1 Network support indicates built-in ethernet and/or wireless networking. Alternatively, many devices may be operated on the network using an external JetDirect print server. Not all network configurations are supported. Please refer to the HPLIP FAQs for more information.
2 USB mass storage only. You may mount the photocard as a storage drive over USB only. Refer to your distribution's documentation for setup and usage instructions.
3 Scan supported means that PC initiated scan using a SANE compatible software application is supported over parallel, USB, or network (depending on I/O connection). Information on digital sending products is covered in note 9, below.
4 Photo supported means that the printer's photo card slots are readable using either USB mass storage (USB only) or hp-unload (USB, parallel or network).
5 Fax supported means that PC initiated fax send is supported using hp-sendfax, once an appropriate CUPS fax queue is set up. Fax support varies on Linux distributions, based on the availability of python-dbus version 0.80 or greater (versions before 0.80 will not work with HPLIP). Click on the model name of each printer to get more detailed information.
6 Copy supported means that PC initiated copying is supported using hp-makecopies.
7 "Services and status" means that ink/toner levels, error reporting, and services such as alignment, and color calibration are available (via the HP Device Manager aka Toolbox).
8 ("Required") A downloadable driver plug-in is required for printing support. ("Optional") A downloadable driver plug-in is optional for printing support and may increase the speed, quality, or other aspect of printed output.
