I beleive part of the reason the bureaus are asking for the older driver is because Windows 3.1 does not include the old Lino 300 and 500 drivers but instead the newer 330, 530, and 630 drivers. I've noticed that on the Lino 300 the service bureaus ask for 2540dpi output but the newer Lino 330 driver only provides 635, 846, 1270, 1693, 2032dpi resolutions. I have sent stuff to Lino 300s using the Lino 330 driver with no trouble although I haven't measured the actual dpi produced. Hope this helps a bit…

Oliver, the DPI setting in the driver doesn't change the DPI setting on the imagesetter. This number (in the driver) is reported to programs that request it for character spacing, postscript fills, etc. The resolution of the imagesetter is set from the RIP or the imagesetter itself and is not over-ridden by the driver.

I understand what you are saying but I don't understand why this works. If the program needs to know the dpi for fountains etc. how do these images come out properly if the Lino changes the resolution? Oliver…

Oliver, things don't always come out the same if the resolution is changed. A graduated fill is very much affected by the line screen and the printer resolution. Something that looks good at 2400 DPI with a 120 line screen will probably show a lot of banding at 1200 DPI. I have no idea if Corel uses the info from the printer driver. I was thinking more along the lines of PageMaker where changing from 1200 to 300 in the printer resolution can change line endings. JohnC

One more thing, the new 3.51 postcript driver of Windows 3.1 has the units of measure backwards and even then there's at least one other ghost… The one that was shipped with Windows 3.1… well don't use it at all… Sometimes one wonders why they fix that which didn't need fixing??? 🙂 Geoff

Geoff, To the best of my knowledge it's the 3.5 driver that has the units backwards and the 3.51 driver corrects this. Donna
