Please help with Dell printer installation

I am hoping to get some help with my Dell printer to get it working with my Mac. I know that Dell is not compatible with Mac, so I have followed the advice of several others to install the corresponding Lexmark drivers. I have a Dell V305 and have installed drivers for Lexmark 3600-4600. This seems to have been successful, expect for I still cannot print. I am having two issues specifically, and I am hoping someone can help me get them resolved.

1. When I try to set everything up to print wirelessly, it seems as if the computer doesn't recognize that it is connected to the printer via USB. I have had some issues with this before having a Mac, but thought it was the Dell laptop's fault (so many issues with it....hence the purchase of a Mac!). I have even purchased a new USB for the printer, since I thought that had to be the issue...well the new one isn't getting me a better result either. I have followed all of the troubleshooting I can come up with for that, and am just wondering if anyone can tell me anything new.

2. When I try to print connected to the USB, the computer seems to recognize the printer, however, I get an error message "unable to read CUPS raster data." I have seen other threads about this issue as well, but can't seem to come up with any great solutions other than installing printer updates, etc. Considering I have installed the most up-to-date driver available, I'm guessing that is not my issue, and I'm hoping someone has advice on this one, too.

I was really hoping to avoid purchasing another printer, since my Dell printer is a good one, and since it isn't very old...I just need to get it working with my Mac!!! Are all signs pointing to the fact that I will, in fact, need another printer?????

I really hope you can help....thanks!!!
