If your Hewlett Packard printer is not listed, it still may be compatible.  The crucial factors are that the Printer Command Language (PCL) is level 3 (check the specification section of the printer user manual or contact Micro Directs customer service department) and it needs a Universal Serial Bus (USB) port.

Please note the printers that have not been tested should work based on their PCL level, however, Micro Direct does not guarantee it. 

If your printer is not listed or on the not tested list and you find it does work with the Micro Direct spirometers, please contact our customer service department at 1-800-588-3381 with this information so we can update this sheet.
