I have recently changed over to CUPS in my Debian system although I don't think that caused the problem.
I have an HP Colour LaserJet 4500 which will happily print a test page from the printer menu which includes colour so no problem there.
However in the CUPS setup the only options I get are 'Grayscale' or 'Inverted Grayscale'. The driver selected is 'HP Color LaserJet 4500 - CUPS+Gutenprint v5.2.3 (en)' and the printer will print only in monochrome.
Any ideas?

It did!

Changing the driver to Generic/Postscript Level 2 now enables me to print in colour but there are still problems.
I can print from Gimp using Gutenprint but using the non-Gutenprint option takes forever. Printing a small low resolution image seems to take 10 times as long, at least, as with Gutenprint and higher resolution and larger take so long I've given up waiting (40 minutes and still going).
The printer is connected via the internal network and I can see the data being transmitted which it was during that 40 minutes after which I cancelled the job.
Why should it take so long?

At a guess the job is getting sent in a format that the internal rip engine is struggling with. The Rip boards in those 4500's aren't the fastest thing on the planet now (although ISTR we filled one of the machines with RAM when you came to collect it, it is still possible to send something that will have the printer thinking for a very long time)
Have you tried installing the official HP printing support (HPLIP) ?

Very occasionally I have had the printer give up because there wasn't enough RAM. It has 64MB at present. Do you think that adding another 64MB would help?
I've never had to wait this long in the past it either prints after a reasonable wait or gives up altogether.

Certainly it would help, it won't really make any difference to the rip speed but it will get rid of that occasional out of memory error.
Kingston sell compatible ram now very cheap for those I think, just check we didn't fill all the sockets first.

I checked the sockets sometime ago when I last got the 'Out of memory' error and there is room for more. The last time I looked the lowest price for 64MB was around £26 now its around £10 but I've also seen it at over £300 ?????
Thanks for the information about HPLIP. I've installed the relevant Debian packages and that has improved some things.
