M401a printing problems

Hi, I have a strange problem with my HP m401a usb printer: sometimes the printer doesn't print. I can see the job in the windows printer queue that says: cannot print - error. The printer is online (ready). I have already updated PCL driver, firmware, usb drivers (I have the same problem with printer connected via both usb2 and usb3 port). I have to shut down my computer (and sometimes it doesn't power off so I have to switch it off manually) and when I restart it the job is regularly printed. What can I do? MB is ASROCK 960GM/U3S3 FX with AMD processor - Windows 7 SP1 64b Professional

Thanks
