Title: Format of file sent to the printer
Post by: bmw on August 30, 2023, 03:03:36 AM
Sorry if this has been answered before.

Out of curiosity, I am wondering what file format is sent to the print driver when printing from a raw file.

That would depend on your setting for spool format.  If you look in Edit, Preferences, Printing Options, the spool format is shown at the bottom.  It's either EMF or raw.

Thanks for your response,

I guess my question was not worded properly.  What format does Qimage use when it sends a file to the print driver?  Does Qimage convert the raw file to either jpeg or tiff format before sending to the print driver.

Qimage, like all Windows printing software, sends device independent bitmap data.  It's not an "image format".  It simply sends the pixel data (raw RGB values).  It's up to the driver how to interpret the data: the driver color management settings determine this.

Thanks a lot for your very quick reply.  I should have know that since I did something like that with a dot matrix printer maybe 35 years ago.
