Hi, found your post below from years ago and it just fixed my problem. Could not print from Outlook 2010 to network USB printer but MS Word would print fine. Any idea what caused this? Remote laptop printed fine to network printer one minute then 30 min later no print in spite of multiple reboots and re-creation of print device on laptop. Would like to know how to avoid this in the future. Thanks for a great tip! Your old post: Try a common fix for this one. Start - Run - type: regsvr32 ole32.dll and Enter. Note there is a space between regserver32 and ole32.dll It reregisters a dll file, if it is not the cause it will not break anything.
