As I have read in many of these and other forum threads, I shared a common frustration, which I was able to figure out. I hope the following will reduce the stress of another. My situation: Desktop Sony Vaio PC running Windows XP Home, wired via USB to Epson Photo Stylus RX600. PC also connected to cable internet via wire to Dlink router with wireless capability. Mac iBook running OSX 10.4.8 connects via airport. Had issues getting the Mac to print to Epson, but could file share via Mac and PC (if you want info on how I went about that, contact me). Solution: On Mac, Finder->Mac help. Search "windows printer sharing"-> select the article titled "sharing your printer with widows users"->manually add printer. If you don't want to read through the entire article, see below. I used my PC IP address to do this. How to manually add a Windows shared printer Open Printer Setup Utility (located in /Applications/Utilities). Mac OS X 10.4.x users: Choose Add Printer from the Printers menu, then hold the Option key while clicking the "More Printers" button. Mac OS X 10.3.x users: Hold the Option key down while choosing Add Printer from the Printers menu. Choose Advanced from the first pop-up menu. Choose Windows Printer via SAMBA from the Device pop-up menu. In the Device Name field, type the name you would like to use for this printer in Mac OS X. In the Device URI field, use one of the following formats to link to the printer: smb://userassword@workgroup/server/sharename smb://userassword@server/sharename smb://workgroup/server/sharename smb://server/sharename Notes: "user" is the name of a Windows user who has privileges to use the printer. "password" is the password of that Windows user. "workgroup" is the name of the Windows workgroup to which the computer sharing the printer belongs. "server" is the name of the computer sharing the printer or its IP address. "sharename" is the shared Windows printer's share name. Tip: You don't need a "workgroup" when specifying the IP address of the computer (such as when the printer is on a different subnet), or if your Mac belongs to the same Windows (SMB) workgroup. Choose the appropriate PPD or printer driver from the Printer Model pop-up menu. Click Add. I hope this helps anyone with a similar problem, and FYI, I have learned quite a bit from forum threads, so thanks to others that post.
