PMView 2000/Lexmark Z51/OS2 prints bluish - Printing from PMView 2000 in OS2 Options

[Guest_Russell Kneebone_*]

Pictures taken on a Canon A70 (3.2 MP - 2048 x 1536) sent to Lexmark Z51 with resolution 600dpi and customer size set to 4608 x 6144 print fine on Letter paper, but same pictures printed with resolution set to 1200dpi print very blue. Not sure whether this is Lexmark driver issue, OS/2 bitmap size issue, PMView 200 issue or mixture.

Same pictures printed "Fit resolution" (i.e. crossways on Letter paper - 4096 x 3072?) print fine in either 600dpi and 1200dpi; actually there is no discernible difference in the output!

Has anyone else come across this issue?

The printer driver does all the dithering and interpolation.

Normally, if you specify the image size in pixels, doubling the resolution should make the image print at half the width&height. However, this only applies if the presentation space coordinates are mapped to the printer hardware. (This is the case with most printer drivers).

Your printer driver obviously uses a virtual presentation space where the coordinates are not mapped to the hardware. Because of this, changing the printer resolution does not affect the coordinates and the printed size. (From what I've seen, Postscript drivers often do virtual mapping like this).

Does your printer give you the option of using either a PCL or a PostScript driver? In this case, try the PCL driver - it will most likely give you native mapping to the printer.

Thanks,
