I tested three ps files: 3pg.ps, 3pages.ps and tiger.ps. They are posted at
ftp://georgeliuyue.topcities.com
user:   georgeliuyue
pass:   password

I have also uploaded HP4345PS.prn and c00719 (ipp control file?) which is 
generated by pstops.
(Created queue, destinate to a file. Print 3pg.ps with 4-up in kprinter)

Thanks
