Software :: Classic Printing Won't Use Letter

In classic, Page Set-up (Laserwriter 8) no longer shows "Letter" or "Legal" sizes. Instead, it shows "na-letter" and "na-legal" and when I select either and print, my printer informs me that paper size "A4" is selected, and, of course, the margins of the printed document are all messed up. Also, my printer stops at each page and asks me to check the paper size. I'm guessing "na" is for "not applicable." Everything worked fine until I installed the 4.4.11 Combo update back in April. I had 10.4.x before that. The Laserwriter 8 Page Set-up dialog box is different than it was prior to the update (although it is a version that's familiar to me from years ago). I've tried deleting the new driver and installing an older Laserwriter driver from another Mac on which I had not run the combo update. Although doing this makes printing fail completely, in the Print Dialog box I do actually see the version of it I remember, and I CAN select "Letter" and "Legal" (and there's no "na-letter" or "na-legal").

If I restart my Mac, it tells me that it needs to update the driver and does so, and then I'm back to "na-letter" and "na-legal" and a different Print Dialog box. I'm printing on an Epson Aculaser CX11NF. Again, it used to work just fine and nothing I know of changed besides the Combo update. Non-Classic printing usually works fine, but sometimes my printer thinks that a document is "A4" when it isn't. Since I end up changing the paper size directly on the printer's front panel (to avoid it stopping with each print and asking me to check the paper size because I don;t have A4 loaded), I'm guessing that this is my fault. Sometimes when printing from iPhoto from another Mac on my network, iPhoto automatically selects A4 instead of letter even though Letter is the default paper size for that Mac. The application is MYOB Accounting Plus. I've had to change the formating of my checks and reports, and I can no longer print on the top inch-and-a-half of the page. I have re-installed the system, the Epson software, and anything else I could think of.
