Last month, I purchased a 24" iMac with OS X (Leopard) which I have been very happy with so far. I also purchased a Keyspan USB to Parallel Port adaptor so I could connect my old Epson Stylus Color 600 printer to my new IMAC, since the Epson does not have a USB port. After I connected the printer, via the adaptor, the Imac immediately recognized the printer and was able to print documents via Gutenprint. However, as of late, I can only print 3 different times before Gutenprint just hangs and only prints 7% of the 3rd document. I restart the computer and then it immediately begins printing the document. I usually have a lot of things I like to print from different webpages so this is a problem. Any suggestions on how to get more stable software?
