Here is one man’s odyssey getting an existing printer installed and running through a new router.
I replaced a Cisco/Linksys router and Airlink print server with a Belkin 750N wireless router. Included with the router are 2 USB interfaces for storage and/or printer devices. The best way to get running requires particular steps in a particular order.
On Mac or Windows the order is the same, only the version of the printer software is different.
1. Remove any existing printer (this is to reduce confusion)
2. Install latest drivers for the printer
a. on mac, get the latest gutenprint drivers from http://sourceforge.net/projects/gimp-print/files
b. on windows, get the latest Epson drivers from http://www.epson.com/cgi-bin/Store/support/Supportdlsurvey.jsp?BV_UseBVCookie=yes&download=ftp%3a%2f%2fftp.epson.com%2fdrivers%2fepson12348.exe&pn=Epson+Stylus+CX8400&pc=Epson+Stylus%26%230174%3b+Series&ft=driver&returnpage=%2fsupport%2fsupDetail.jsp&returnparams=%26infoType%3dDownloads%26oid%3d90342%26prodoid%3d63069506&licenseoid=17774
NOTE: do NOT setup a printer at this time.
3. Install Belkin USB Print and Storage Center software (not Storage Manager)
a. on mac, get it from http://cache-www.belkin.com/support/dl/phase1/InstaLAN_Belkin_402_F7D3302.dmg
b. on windows, get it from http://cache-www.belkin.com/support/dl/phase1/InstaLAN_Belkin_402_F7D3302.exe
4. Reboot (yes, even on the mac)
5. After restart, confirm you get the “…found a new printer” dialog
6. Click “Use EPSON USB2.0 MFP(Hi-Speed)” from “Networked USB Devices” on the Belkin menu (systray or menu bar)
a. a Windows based example can be found at http://en-us-support.belkin.com/app/answers/detail/a_id/3796/~/setting-up-your-printer-using-print-zone
7. NOW, if its needed, add the printer, choosing the appropriate driver for the printer (which you did in step 2)
a. for mac, follow the instructions at http://support.apple.com/kb/HT3049
b. in my case, I chose EPSON CX8400 Series.
