I'm using a PowerBook G4 running Panther (v10.7.3), with an HP LaserJet 1200 connected either directly by USB or through AirPort Express. My problems started as a result of one of two simultaneous events. It began when I decided to become efficient. So I bought a) an A5 Filofax into which I could insert alphabetically listed addresses, and b) an AirPort Express. I set up the AirPort Express, including plugging in the USB from the printer to it, and adding this wireless printer as "HP LaserJet 1200 Living Room" (I couldn't see any way to change the name) in Printer Setup Utility. I would have liked to use a different name, to make it easier to distinguish the two LaserJets from each other - the driver that operated when I had the printer plugged directly into the computer by USB, and the driver that operated through the AirPort network called Living Room. All seemed well; I was pleased with how easy it was to print off my normal A4 documents. I set to work and spent a day typing up my 29 pages of addresses and making them properly alphabetical, setting up the document as an A5 one. Then I put some A5 paper in the printer and pressed Print, choosing the "Living Room" LaserJet 1200. Printing started halfway down the page, and leaked off the left-hand edge. I spent the rest of the day, and the hours between 4am and 6am last night, trying *everything*. Finally I thought of something else. I plugged the printer directly into the computer, chose the USB version of the printer and pressed Print, and it printed off happily. So obviously the "Living Room" version was corrupt. I deleted it. Then I went to print out something I was writing and wished to edit, still using the USB directly plugged into the computer. It printed it out starting halfway down the page and leaking off the bottom edge. I deleted this printer too, and then pressed Add Printer (both in Printer Setup Utility). The Setup Utility offered me two identical options of HP LaserJet 1200, among other options. I chose one and tried. It printed off the edges. I deleted and chose the other and tried. It printed off the edges. I deleted the Printer Setup Utility Preferences and restarted, and went to Add Printer again. Again it offered me two HP LaserJet 1200 items. I tried Manual; it told me that there were multiple versions of the printer description. I searched for and deleted the printer description (only one) for HP LaserJet 1200, and also for HP LaserJet 1220, just in case, and restarted. I went to Add Printer, and there they were again, the two HP LaserJet 1200 items. I tried using an Apple LaserWriter item instead. Still printing off the edges of the pages. I'm now officially stumped. What have I not done? What should I do? What is causing the problem? Sorry for the long post, but I wanted to be clear about what I'd tried and not tried. If there's anything I've not tried.
