Printout is a blank page

Here is another student's work. Part of the page prints but the rest is lost.

running Windows 7, 32 bit, Inkscape 0.48.3.1, HP Deskjet 895 printer

- problem confirmed with SH Justin C. I get a head, two ears, but no body, no arms or legs, no text name

fwiw, if I save this image as a pdf file, then the pdf file is exactly the same as my printed output, same parts are missing.

Same result if converting 'SH Justin C.svg' to PDF using rsvg-convert from librsvg 2.36.1, independent from Inkscape (PDF attached).
-> it seems that a cairo-based conversion (SVG -> PDF) stops if encountering "invalid" SVG code.

Possibly related:
Bug #534679 “Cairo-based export not exporting all elements”
<https://bugs.launchpad.net/inkscape/+bug/534679>

The attached modified version of the file 'SH Justin C.svg' saves ok as PDF (no obvious missing elements).

One (or more) of the 17 remaining objects on the now hidden layer 'Layer 1' obviously stop further processing of the SVG source when exporting to cairo.

The user didn't intend to put anything on a hidden layer. How do I find outbif something is hidden by accident? How do I unhide it?

You misunderstood my comment (which was intended for internal bug triage - to narrow down the issue - and not directed to you as user). As mentioned, I had edited the original file (for bug triage) and reorganized the content into two layers:
a) one with all elements that visibly belong to the intended drawing content and are exported to PDF without error,
b) one with remaining objects which apparently had been - unintentionally (?) - scaled or otherwise transformed by the user in such a way that they don't or only barely render as visible objects, but can stop any further processing of the SVG content in cairo-based export or printing routines.
