I don't think the MorphOS Printing system that is in the works is intended for foo2zjs, which, as far as I am aware, is an open source printer driver for printers that use the Zenographics ZjStream wire protocol for their print data, such as the Minolta/QMS magicolor 2300.

However, if you have a HP CP1025NW Colour Laserjet printer, then it is shown on the printer specs as having:

Print Languages, Std HP PCL 6, HP PCL 5, HP postscript level 3 emulation

If that information is correct, then you can use it with the current MorphOS Printing Beta from Zukow with a fairly standard Postscript PPD file and it should print OK, just some manual installation files to copy from Zukow's archive.
