As I stated:
"It is not the printer drivers(1), or the network connection(2), or the D&P config(2), or the Word Data key in the registry."
(1)=I have uninstalled and reinstalled the ptr drivers 4 times.
(2)=I can print TXT files and pictures via Windowz Picture viewer and MSO OIS.

I have uninstalled and reinstalled MS Office.

Outlook says the printer isn't ready - after the job flashes in the print queue
Word & Excel appear to print (job flashes in print queue) but nothing comes out the printer - any docx/xlsx files.
I JUST FOUND ONE DOC FILE THAT PRINTED!!!!!!!!!!!!!!!!!
So what is the dif in the file????????

When that file prints it remains in the print queue for a few seconds, the other files flash in/out in about 1/2 sec. - all r one page docs. This one has different font. If I make a change to the file it won't print. ALL files print from my computer.

A Excel says there is an error. -- low memory, cable, network, drivers, ....
xlsx or csv files.
