Resizing a JPEG image for printing (usingCUPS Library)

[Tom Morrison]

Hi Michael...

It never got to more than 1 page - I just assumed that it would...

Even though it has a photo tray, its not going there, but, as you indicated
I was NOT sending image/jpeg for document format - I will try that next and
report back!

Thank you Michael!

Tom

Just be sure to specify a document-format value of "image/jpeg" so the printer knows what you are sending it - not all HP printers support auto-sensing via IPP.

The "ipp-attribute-fidelity" operation attribute can be used to force scaling to that size (although I think most HP inkjet printers ignore this when printing from the photo tray and just use the detected size...)
