I'm printing bitmaps on a report, which consist of the digits zero through nine, rotated 90 degrees (I needed to print some ID numbers sideways on an otherwise portrait-mode printout -- the output is on paper forms that are filed sideways). I created the bitmaps in Microsoft Paint, and saved them as black and white. They work fine for me, both on my Canon Bubble Jet and when I send the output to my fax driver. However, on my client's HP 4SI, they print with a grey background, instead of white. Any thoughts on this would be appreciated!
