There has been much discussion on printing from within CVI, but 99% of the time it turns out to be a driver problem. Without bashing HP too much, their drivers are not the most reliable things in the world. As to the problem you are seeing with this specific printer I cannot say, but you could try using another driver. Does it work to other printers on the network ? (Implies a driver issue).
There is an archive of CVI postings http://welcome.to.cvi/ A search of that may give you more info.
