Yes, this is a known problem with Cocoa printing from a Carbon
application. We hope to have a fix in a future version of the OS.

I want to print some text that will almost surely fit on one

How about running it in the debugger and pressing pause? You can
examine the call stack. My bet's on an infinite loop. Any takers? ;-)
Here's the call stack, none of which is my code except for the last
line.
mach_msg_trap
mach_msg
CFRunLoopRunSpecific
CFRunLoopRunInMode
RunCurrentEventLoopInMode
ReceiveNextEventCommon
_AcquireNextEvent
_RunAppModalLoop
RunAppModalLoopForWindow
-[NSApplication _realDoModalLoop:peek:]
-[NSApplication runModalSession:]
-[NSConcretePrintOperation(NSInternal)
_isCancelledAfterHandlingUserEvents]
-[NSView(NSPrintingInternal) _printForCurrentOperation]
-[NSConcretePrintOperation _renderView]
-[NSConcretePrintOperation runOperation]
-[MyController printInfo]
I tried to reproduce the problem in a toy app, and naturally I
couldn't. So apparently something that I didn't think was relevant,
was. Possibly the fact that this is running in an app with a Carbon
event loop.
