Set up: Epson Stylus Color 3000 with Network Interface Card (NIC) in 10.5 Leopard. It prints ok from 10.4 and another computer on 10.4 but the 1.7a driver doesn't work in 10.4 and hasn't been updated since 2003. When trying to print it buffers data through then goes to Printer Paused. If I watch close I can see /usr/libexec/cups/backend/ipp failed Even updating to the 5.1.4 Gutenprint driver <a href="http://downloads.sourceforge.net/gimp-print/gutenprint-5.1.4-UB.dmg?download">gutenprint-5.1.4-UB.dmg</a> still left me with a paused printer This backdoor process gets it printing, but the queue has to be cleared manually. Go to the address of the Epson SC 3000 printer in Safari http://192.168.123.115/ Under the information heading on the left click on IPP Copy the line next to IPP URL http://192.168.123.115:631/EPSON_IPP_Printer Back in Safari, go to http://localhost:631/ which magically opens the back door. [I have NO idea how you're supposed to find THIS on your own!] Either click on the "Add Printer" button below the Welcome! banner or click the Administration tab and under the Printers heading click on "Add Printer" Name: SC3000 [no spaces alllowed] This is the queue and how it will be listed under the printer tab in CUPS Location: Study Description: Epson (This shows up in Print & Fax as the printer name) Click Continue, wait 7 seconds From the Device: popup menu choose Internet Printing Protocol (http) or (ipp) Click Continue Paste into Device URl: (write over the "http" already there) the address you copied from above http://192.168.123.115:631/EPSON_IPP_Printer Click Continue From the Make: popup choose Epson Click Continue Scroll down the Model: listing (about 2/3) and choose Epson Stylus Color 3000 - CUPS+Gutenprint v5.1.4 (en) Click Add Printer In Preferencesrinte & Fax uncheck Share this printer (it's a network printer) CUPS doesn't remove jobs from the queue. You have to delete them manually before the next job can go through.
