I have written a program which peforms editing on image-files. I am currently using the available Java classes which
interact with printer-drivers in oder to get he resultant images printed. The standard Java classes that interact with
image-objects all expect that the format of the images to be at 100 pixels-per-inch. Unfortunately, when the printer
class sets up a print-job, it transmits the image to the driver as if it were at 72 PPI -- and it (I assume) informs the printer-driver that the desired output format is 72 DPI. My image is seriously goofed-up by this process.
My intension is to eventually write a new (and hopefully better) class to perform the necessary software-connection to the available printer-driver(s).
I actually have 2 general questions ---
1) Does HP hve any tutorial software that I can look at to get a better idea of what is required for interaction with any printer-driver?
2) Does the standard HP RTL provide a capability to instruct the printer-driver in what DPI to use in setting up the print-job?
