I tried to print ps file with 4-up first to a file, and then print the file 
with -o raw.
It generates the same result. one page came out with gabbage.

As stated in senario 2 and 3 in my previous email, I print text file with 
4-up directly and print text file with 4-up to a file then print to raw 
queue. Both cases worked perfectly.

I have Michael's CUPS book, but I couldn't find any details on how CUPS 
handles ipp attributes.

I also suspect maybe the 4-up is supported by kprinter, but when I print a 
text file, cups involkes texttops and pstops. It doesn't look like there's 
any room for kpriinter.
Maybe 4-up and other ipp attributes are handled only by texttops filter? 
Again, is there any documentations on how cups filters, backends handle ipp 
attributes?


BTW,  orientation setting in kprinter only works for text file, but not ps 
file.

Thanks
