Mike,

The Auto Roll feature could still be super useful to HP printer owners:   You could add images to a job while in Auto Roll mode, and then - at the end - you would know exactly how long to make the Custom Page in the driver!

Not as slick as drivers that support custom media length, of course, but much better than any other method.   This might be the foundation for using Auto Roll Mode to generate a TIFF export too?

One way I imagine it could work is that the user selects a "fake" QImage printer in the Printer dropdown, which allows the user to set the paper width to anything reasonable (e.g. 24"), and let Auto Roll control the length.  Once user has finished adding images, she will know exactly how long the paper needs to be.  User could then choose to either export the job as a TIFF for printing later at Original Size, or select a "real" printer (e.g. an HP printer) in the dropdown and manually set the length of the Custom paper to the size calculated by Auto Roll.

QImage could even put the length into the clipboard so it is easy to paste into the HP printer driver later, LOL.

This would be totally awesome!

That's what I do today -  I have defined a single 24" x 40" page, which I add a bunch of images to.  If I need more paper, I modify that specific custom paper size in the driver.  When ready to print, I tweak the size and print.  I hadn't noticed the feature where QU displays the actual length precisely, that's very helpful.

Wouldn't it be cool if one of the driver's custom paper sizes could be "reserved" for QImage to modify...
