HP LaserJet 1320 imageable area problem in PCL*

[Matthias Andree]

I have a LaserJet 1320. In PostScript mode for A4 paper, the imageable area seems correct, in that I get a complete outer frame rendering on a CUPS (1.3.x) test page. However, in PCL mode (PPD file header below), the imageable area is too tall (vertically), so the upper border of the upper rule is cut off.

The PS driver uses lower-left 4.2 x 4.2 mm² and upper right 205.7 x 292.7 mm² (1200 dpi). The PCL driver uses lower-left 6.4 x 4.9 mm and upper-right 203.7 x 292 mm (600 dpi). It is not clear to me why the PCL driver would suffer from cropping if it indeed has a smaller page size than PostScript, thus the upper start of the page would actually below (so this seems counter-intuitive), but that's what I see. Might there be a vertical offset that isn't printed in CUPS's test page?

If so, then the vertical offset should be adjusted so that the page appears a small amount closer to the bottom.

I've been trying to use PCL (rather than PostScript) in an attempt to overcome PostScript rendering performance issues.
