You will need to install the Printer Status and Alerts software once on each computer for all supported HP LaserJet printers to be connected. Not all printers are supported in each software. Please read the Late-Breaking Readme file for printer and software support, information about the installation and use of your Printer Status/Alerts and Internet enabled supplies ordering software. Some printers may experience slower performance due to the different ways that some computers and printers handle bi-directional communication of the parallel (LPT) interface. Some larger, more complex jobs may need more time to process and print due to the increased communication traffic over the parallel interface.
