Outlook tells you the printer isn't ready when it really is? Does that happen always, often, or sometimes?
Excel has a similar problem though not exactly the same? None of your other applications software has that problem?
After Word, Wordpad, and Acrobat jobs flash in the queue, the print jobs just disappear as if they had been printed?
You have a Word document that prints but if you change the font in Word and print again, it doesn't print? If you change it back to the original font, it prints? When it doesn't print, where is the problem (Word won't send it to the printer? It goes to the printer but the printer refuses to print it and it stays in the queue? It goes to the printer and then disappears without being printed?)
When jobs don't print, do you ever get any kind of error message?
Is your computer the only one on the network that has these problems?
Are the problems affected by other users' traffic on the printer concurrent with yours?
Is the software on all of the computers identical (eg, IT person loads the same package on every computer and does the same updates on every computer?
Have you consulted an exorcist?
Try this test: Download and install one of the free PDF printer drivers (a good one is Cutepdf Writer available free here:
http://cutepdf.com/). If you're not familiar with these, they create a phantom printer in your printer list. When you use this printer, the output is a PDF of your document which you then tell it where to save. I have not yet found any kind of output that was not faithfully preserved as if you converted the original document to PDF.
Use this as the "printer" for every application that is giving you problems and every type of document that gives you problems. In the case of the Word file with the font issue, print a version of what does print and what doesn't print. Generate a collection of PDFs that represent documents that are problematic.
First question: are you able to "print" everything that is a problem on the network printer?
Second question: does the PDF output look like what it is supposed to look like?
Then, take a random sample of the PDFs and print them to the network printer using Acrobat. If you can open PDFs with your version of Word, open a few of the PDFs that represent problem documents for Word and print them to the network printer.
Can you print any of the problem documents this way that you can't print when you send the original document directly to the network printer?
Can you reliably print web pages from your browser (on the network printer)?
