Problem with Epson 4450

[steve_nfi]

I have an Epson Stylus Pro 4450 which worked fine attached to an XP machine but now we have upgraded to Windows 7 we are having problems. I have installed the correct software and drivers from Epson but when we try to print a test page we get a box coming up saying that it is trying to print from a different port. Does anyone have one of these printers or have had a similar problem with W7.

 

Also does anyone have any recommendations for a colour laser that we can put in our art department. We currently have an HP CP2025 which also isn't working well since W7. This keeps failing with memory errors, so I presume that something with a large amount of memory will help.

 

Any suggestions will be much appreciated.
