Hi Dave
If I understand it right the postscript driver is the software interface to the hardware(printer) so the application is responsible for delivering postscript output compatible with the drivers requirements.
Looking at the raw postscript files generated by OO115 and AOO4 from the same document when printed to file I am fairly sure that the printing program affects how the postscript is generated as the files are different sizes and have different contents - and they are using the same printer driver.
The output from AOO4 has duplicate sections which may or may not affect output.
Interestingly the output from OO115 shows
%%BeginFeature: *ColorModel Gray
<</cupsColorSpace 0/cupsColorOrder 0/cupsBitsPerColor 8/cupsPreferredBitsPerColor 16>>setpagedevice
%%EndFeature
where the output from AOO4 shows
%%BeginFeature: *ColorModel RGB
<</cupsColorSpace 1/cupsColorOrder 0/cupsBitsPerColor 8/cupsPreferredBitsPerColor 16>>setpagedevice
%%EndFeature
As OO115 prints in colour and AOO4 in greyscale I think I expected OO115 to show *ColorModel RGB and AOO4 output to show *ColorModel Gray.
I wonder why the AOO4 output has "/cupsColorSpace 1"... maybe related to the *ColorModel RGB bit...
As an experiment I changed the *ColorModel RGB to *ColorModel Gray and /cupsColorSpace 1 to /cupsColorSpace 0 in the AOO4 output, deleted the duplicate lines, saved the file and attempted to print it using cups:-
[J:\CUPS\BIN]lpr -P RX585 "I:\Users\peter\HOME\My Documents\OO4_EpsonRX585.PS"
No, No Colour Output! :-(
Not knowing much about postscript I doubt if I can "debug" the AOO4 output to find and correct any error(s). I see AOO4.1.1 for OS/2 is just about to go GA so I will see if this problem has already been fixed before investigating further.

Pete
