Thanks Stanley,
Despite the officially stated printable size limit of 30K x 30K
pixels from Photoshop for Mac and Windows both, it appears, from the
experience of many users including myself, going back many years,
that the actual limit is roughly 16,000 pixels on the Mac, though
this seems to vary a little bit due to things that affect available
memory.
The current manisfestation of this bug is that after one says
"Print", and the progress bar ends, the file fails to show up in the
printer's queue.
I found a simple workaround for this limitation, which apparently
also allows printing to more than 30,000 pixels. I did a test at
35,000 on the long edge and the file successfully showed up in the
printer's queue, so the limit is probably way beyond 30,000, though
driver inch dimensions or other limits may still apply, such as
Epson's driver's approximately 92" limit.
Adobe says that the problem is an old bug in QuickDraw and that they
are not going to address this with an update to CS3. Needless to
say, if Adobe is right, it's unlikely that Apple would fix it either.
1) Convert the prepared (flattened, sharpened, etc.) printing file to
printer space in Photoshop.
2) Choose "Don't Color Manage This Document" in the Assign Profile...
dialog (meaning "Do color manage this document in every way, except
don't embed the profile when saving it.")
3) Save the file as a TIFF.
4) Open the file in Apple's Preview application, choose to Print, do
the necessary page setup stuff, and select the Advanced printing
options button, then set all the usual driver settings and go. Voila.
If you open the file in Preview and it has the printer profile (or
any other profile) embedded in it, Preview will, without telling you,
convert the file from that profile to your display's default profile
(a profile which you can identify in ColorSync Utility), totally
ruining the color, before sending the file off for printing. The
logic was that if you're printing, you surely want to be in monitor
space and let the printer driver handle the file as though it were.
Preview should include a message with an option: "We will now convert
your file from its embedded source profile "[name of profile]" to
your default monitor profile. OK Don't Convert"
And it should offer to convert to the current system profile, not the
display's default profile. Doing profile to profile conversions on
files without even telling the user is what I would call incredibly
rude. It took quite a while to figure out why printing from Preview
was not working right and to therefore realize that merely not having
the profile embedded was the best way to avoid doing a conversion.
File this under "Printing over 16,000 pixels on a Mac" (without
resorting to using a RIP, which avoids this limit and also the inch
size limits).
