I'll get a new print server and report back here as to whether this resolves my problems. I will look into a new printer as well, though I have no complaints about mine and, as I recall, it cost $300 (it is one of those all-in-one jobbers). Thanks for your help on this.
P.S. I wonder why pyqt is not available to me. I'll fiddle with this a bit and will check my other machines to see if they yield different results.
