It is not Mac compatible. I was promised that it works with MacOS, and now I get that it was not true. I force it to work with CUPS http://www.cups.org/ and Gutenprint http://gutenprint.sourceforge.net/p_Features.php3. It works with PPD (driver analog) "Generic PCL6". And there is one problem - it doesn't print color. So I think that I have to find PPD for another printer of the same manufacturer as the Dell's 3000cn manufacturer. But I have no idea what manufacturer builds Dell 3000cn.
The entire 3000/3100cn laser printer line are rebadged Fuji-Xerox of Japan products, unfortunately that company has virtually no presence in North America as far as I know. Another hint is some of these printers are also rebadged as Epson products in Europe and elsewhere, I believe as their 1100 series lasers. You can search for drivers that might work via those 2 companies. Good luck.
Thanks Jonathan! I have read that thread, and I have successfully installed "HP Color LaserJet 5000 Foomatic/hpijs". But pxlmono PPD (www.linuxprinting.org/show_driver.cgi?driver=pxlmono) doesn't work with my printer. I think that PPD was modified since you download it (with this: www.mit.edu/~jik/3000cn/foomatic-3000cn.patch.html). Now it may works with Linux, but not with MacOS. Would you please send me original PPD to avp at esmile dot ru?
I moved my printer today and had to re-install on a different Mac... this was for the Mac by the way, not Linux. The PPD works fine, but you have to make sure you install espgs-7.07.1.ppc.dmg and foomatic-rip-220.127.116.11.ppc.dmg.
It works! I don't understand what was the problem, but I did the same and the printer printed "Kernel error". Now I repeat installing of espgs-7.07.1.ppc.dmg and foomatic-rip-18.104.22.168.ppc.dmg and that error was fixed. It prints with the same quality as Windows driver. Thank you!!!
