Richard,
It's hard to tell exactly what you are seeing without the details.
But if you are printing 2 images vs 1 a number of things will take twice as long.
The first thing is a PDF file is created by Print-Tool & OSX to send to the print system.
Then the cgpdftoraster has to rasterize the whole page -- data includes all the white borders.
If you connect via USB direct the printing and cgpdftoraster will work simultaneously
but if you use one of the ethernet connections it buffers up the whole thing before
starting the printing. And of course if these intermediates add up to anything close
to your main memory size, things can get much slower due to disk I/O.

Walker,
If you have any info about new or replacing cgpdftoraster I'd be interested in any info.
As far as print lengths I think the only place that limits this is the actual print driver so
I doubt Print-Tool has to do with this. The main example for QTR driver is the
3800/3880 where the Epson driver limits to about 37inches and QTR driver allows much longer.
Usually the issue is because of roll paper support in the hardware.

cgpdftoraster is multithreaded but there is some limit there. I’ve only seen it go to 4 or 5 threads and it’s bandwidth is limited. I’ve filed a bug report w/ Apple but no feedback.It’s a proprietary Apple cups filter basically. Linux has recently migrated to a faster filter and Apple itself uses something else now (Adobe used that) but not sure if that will be all that good w/ PT.It’s a huge issue with another program I ran at LightWork community lab called PaperCut. Render times are slow. It’s basically the thing that used to delay Photoshop in the 9600 days . . . .Roy can confirm this, but I think it’s how we get passed 90” print lengths with PrintTool (I’ve been doing up to 150 inches easily)??basically, cgpdftoraster is old-school CUPs and it’s slow but super stable . . . .Actually it might be worth it to suck it up and be ok with spool times . . .best,WalkerOn Feb 9, 2016, at 7:18 PM, richard@...
