I have a strange problem that seems to recur and clear but I have no idea how to get the problem cleared when it happens. Here is how it goes. Normally I have no trouble printing simple pages to my printer which is attached to the network via cable to the router. Network is wireless. I have a webpage that generates pages that I want to print duplex (the printer does support this) I also want to manually feed the paper for this job. I go to the print preview set it all up and print one page everything works fine. Then I can no longer get to the printer properties to change to and from duplex or to or from manual feed or change type of paper number of pages etc. Click on printer properties it just blinks at me and does nothing. Sometimes it will print basic single pages other times the requester goes away but it doesn't print. Sometimes it tells me some printer functions are not currently available. At some point it apparently clears itself but no idea how or what as I have cleared all the print_ bits from the profile, i've rebooted and it still does this. But the last time it did this was some time ago so I had forgotten about it and the first page today worked fine. I can print the duplex pages fine from chrome or IE and more than one of them.
