Comment 2 for bug 41789

Hmm... Looks like this may be due to flakiness in what Samsung has delivered. A bit of googling led to an explanation of their PPD file being incompatible, http://www.linuxprinting.org/pipermail/general-list/2006q1/007279.html

That definitely seems to be the case on my system:

$ cupstestppd /usr/local/linuxprinter/ppd/C/ML-1610spl2.ppd
/usr/local/linuxprinter/ppd/C/ML-1610spl2.ppd: FAIL
      **FAIL** REQUIRED DefaultImageableArea
                REF: Page 102, section 5.15.
      **FAIL** REQUIRED PageRegion
                REF: Page 100, section 5.14.
      **FAIL** BAD Product - not "(string)".
                REF: Page 62, section 5.3.
      **FAIL** Bad Resolution choice 600!
                REF: Page 84, section 5.9
      **FAIL** Bad Resolution choice 300!
                REF: Page 84, section 5.9
        WARN DefaultLinuxGDIBand has no corresponding options!
        WARN PCFileName longer than 8.3 in violation of PPD spec.
                REF: Pages 61-62, section 5.3.

So I've hacked the PPD file from Samsung, leaving only the warning about DefaultLinuxGDIBand. (I guess that could be looked up.) The test page prints okay.

I wonder if the folks at Samsung know about this.
