Digital BW, The Print

Tom,

I asked because AFAIK when you print with Qimage, it interpolates the image 
up to the ppi used internally by the printer driver. For epson desktops that 
is 720ppi, for epson wideformats 360ppi, and other printers such as HP and 
Canon use different values, eg. 600ppi. All that info is I believe, stored 
in QImage (or it gets it from the printer driver each time), which is where 
the 'intelligent interpolation' and 'smart sharpening' come in.

If you use another driver such as QTR to print with, you presumably have to 
know what ppi it prefers internally, in order to be able to use Qimages 
interpolation and smartsharpening to its best advantage.

I'm not saying you can't use Qimage and QTR, just suggesting it might not be 
any different to using PS and QTR; you have to choose the interpolation and 
sharpening instead of QI doing it for you when it prints throught the normal 
printer drivers.

You need Mike Chaney or Roy Harrington to clear it up.

That's a good question.  Possibly but it certainly doesn't ask for the
printer when you print to file.  I'm not certain it needs to know the
printer when you print through QTR because you specify a printer
there.  That's not a good answer I know.  Maybe I'll ask over in the
Qimage group.
