I just purchased a Canon iP5200R printer and am having serious problems getting my setup to work properly. I have a wireless LAN at home: 1) G5 single (OS X Tiger 10.4.8) physically connected to a Linksys wireless router with an ethernet connection. 2) MacBook (OS X Tiger 10.4.8) connected wirelessly to the LAN. 3) Dell something laptop XP thingy. The Canon iP5200R printer can be connected either wirelessly, by ethernet cable or by USB cable to the LAN. I started out with a wireless connection from the computers to the printer (my G5 has an Airport card). All of the computers looked like they had been configured properly, but I only managed to print one test page from the Dell to the printer after setup. Setup requires that you first have to connect the printer physically to each Mac with a USB cable. Then the "new" setup (which is actually the same for both Macs) is "transfered to the printer. Now I have tried to connect the printer physically to the router by way of an ethernet cable. After having had to redo the setup by connecting the printer to the G5 again with a USB cable, everything seemed to work - except printing. Now at least, OS X can detect the printer and so can the Canon utilities. Unfortunately, I still get an error number 300 saying that the printer does not respond. If I stop the job and resume it, the driver keeps spinning it's wheels trying to open a connection to the printer, but nothing happening. If I go into "utility", the printer is recognized from the get go and the printer is also recognized if I go into the printer configration. At this time, I am only working on getting the G5 to work. That means that I have the following configuration: 1) Only "wired LAN" is configured with "automatically get IP address" set. The address seems to be set to 192.168.1.106. 2) There is no Mac address or IP address control set. I really need some help on this as I am out of my depth. Here is some of the info the printer configuration: Canon iP520OR Network Configuration Page Printer : iP520OR Firmware Version : 1.02 Wireless LAN : Disabled Standard : IEEE 802.llg Network Type : Infrastructure Link Status : Inactive Signal Strength Link Quality Transmission Rate TCP/IP Mode IP Address Subnet Mask Default Gateway Wired LAN : Enabled Link Status : Active Transmission Rate : 10OMbps TCP/IP Mode : Auto Cheers, Brian
