When printing a document with Pages I find no ink saving options of the kind I have on my PC, with Microsoft Word, and the same printer (HP photosmart). The options I refer to are Fast Draft, Everyday, Normal, Best - which regulate the amount of ink employed for a print.
A short introduction :
Microsoft Word for Windows passes printing commands through the Graphics Device Interface (GDI) on Microsoft Windows XP. GDI accents only three colourant components Red, Green, and Blue - it does not accept other colourant component models (Cyan, Magenta, Yellow and Key, for instance). Inking is controlled by hardcoded curves in GDI printer drivers.
Colour cannot be controlled in the GDI printing pipeline except by bypassing the hardcoded curves in the sense that controlling colour presupposes that the convertible colourants that can reproduce a coded colour can be computed by the system. Microsoft has moved away from this model in Vista in 2007, and Apple moved away from this model in 2001.
The current models introduce the concept of controlling colour, that is, you keep the coded colours constant by computing the convertible colourants that will reproduce them in the given printing condition. The concept of controlling colour is embodied in the intelligent separation model of the International Color Consortium which uses the file format of ColorSync 2.
A short explanation :
In a colour controlled system, you need an ICC type PRTR Printer profile for the paper and ink combination of your printer. The data space of the PRTR Printer profile may be CMYK for publishing applications or RGB for productivity applications. You also need a printer driver for the make and model of your printer, in this case a Hewlett-Packard PhotoSmart. You install the ICC type PRTR profile for the paper and ink combination of your printer in the ColorSync Utility, but bear in mind that as the amount of ink and the kind of paper is characterised in the PRTR Printer profile, colour matching is dependent on whether the characterisation was for e.g. Best (which would be what you want for the largest gamut possible since the more ink you lay down the larger the gamut you get).
In your case, your PhotoSmart printer presumably presupposes lowend sRGB as input when printing to specified HP papers. Whether the results are satisfactory is an open question. You may also try the HP site to see if HP offers specific ICC PRTR profiles for specific HP papers that work with your make and model of HP printer. Or better still, find a photographer who is willing to characterise your printer/ink/paper combination of choice using a proper spectrophotometer. Inkjets are surprisingly stable over long periods of time and your custom ICC profile should last for as long as HP keeps the ink recipe and paper production process stable.
Professional HP printers now come with a GretagMacbeth spectrophotometer built into the printer carriage along the same lines as the Image Control units of Heidelberg Speedmaster presses that have had GretagMacbeth spectrophotometers with an array of optical fibres to take readings across the sheet.
So, your problem has nothing to do with Pages because pages uses the intelligent separation model of the International Color Consortium just as Pages uses the intelligent composition model of the Unicode Consortium (which by the bye is based on the SFNT Spline Font model of Apple TrueType 1).
