Description Jack Moffitt 2000-09-24 22:22:56 UTC 
Originally reported by: nobody@users.sourceforge.net
I found a misc bug on gs6.01/src/gdevsppr.c for Sun's SPARCprinter.
This bug seemed to appear in newer version (>6.00) of gs because gs5.10 did not have this bug.
Please collect line 129:

lpvipage.resolution = (pdev->x_pixels_per_inch == 300 ? DPI300 : DPI400);

to

lpvipage.resolution = (pdev->x_pixels_per_inch == 300 ? 300 : 400);

(or some more better solutions are also welcome)

This is fairly puzzling, as the http://www.stat.yale.edu/~emerson/lpviio.h file seems quite clearly to want DPI300 or DPI400 in the resolution field of the lpvi_page structure.

I think this may be a situation in which different versions of the SPARCprinter driver have different requirements. As you note, gs5.10 use 300 and 400 rather than the DPI300 and DPI400 constants. However, it's likely that this wasn't working for somebody, judging from this change note in History5.htm:

        - Setting the resolution on the SPARCprinter didn't work.
(gdevsppr.c)

Perhaps the best way to resolve this bug is to document the fact that different versions may require different invocations to set up the printer.

It is unclear to me what the correct behavior should be.
Thus, I have documented this uncertainty. For more
