HP PML Driver Service. Background task installed by the drivers for a variety of HP printers, ranging from the HP PSC 2100, 2200, 4100, and 6100 series of multifunction printers, to DeskJet 6600 and 6800 series, PhotoSmart series, All‑in‑One OfficeJets, etc... This task handles non‑printing related two-way communications between the PC and the HP printer. Typically, on DeskJet and InkJet printers it will handle status-type communications such as ink levels, paper‑empty conditions, etc..., and will feed that information back to an HP icon in the System Tray. In the case of more advanced printers, such as All‑in‑One printers or PhotoSmart printers, it handles additional non‑printing related communications such as scanning and photocopying events, access to the card reader, etc...
Because of its role as, effectively, a printer status information gathering task, this task should be left running since, without it, you will not get useful information from the System Tray HP icon for your printer which will think the printer is disconnected. However, some versions of this task have been more than problematic, with serious conflicts with specific software packages (Sage Accounting with some versions of this task), or with “Unable to Start driver” errors on boot-up. If you experience problems with this task, first ensure that your firewall allows this task to communicate – if your firewall is preventing the task from talking to things external to the PC then this task will not work properly (Note: at the time of writing, 25‑Sep‑2005, the Windows XP and Norton Firewalls allow this task to communicate by default, so you should not need to configure them). Next, if you still have problems, see on our Drivers page if there are newer drivers for your printers which might correct the problem. If problems still remain after the above then disable this task on the Startups tab of The Ultimate Troubleshooter in Windows 98/ME, or, in Windows 2000/XP, locate it on the Services tab and set its Startup Mode to Disabled.
As Hewlett‑Packard themselves state : “Most if not all printing functions will work without it, and print quality and speed are not affected by this. However, other functions of the printer driver may be disabled. If a feature is noticed to be missing, the PML driver service can be manually started as described above. Remember to disable the PML driver service again before restarting the computer”.
