This means that what I send to CUPS is printed to printer without changes. We have problems with Postscript printers from HP and printing Postscript documents converted with psnup or psbook in duplex mode along narrow page. This documents are correctly printed after transformation with ps2ps or ps2pdf && pdf2ps or something like that.

The thing is that CUPS requires PostScript jobs to be fully DSC
compliant.
But the output of most of these psutils violates the DSC conventions up
to
a certain extent.

A workaround may be to print those psnup-ed jobs as raw jobs.
