HP Designjet A/B/600 Printers - Thin, Lightly Shaded Lines Disappear
When plotting a drawing in enhanced mode, some of the thin, lightly shaded lines disappear.
Lines will disappear, generally in the vertical direction only, when single pixel, 0.13 mm (thin) line widths are selected. Switching in to Final mode this should correct this issue. This issue appears when the printers firmware is older than 3.2.
To check the printer's firmware, go to Utilities on the front panel of the printer and then scroll through Statistics to verify the code revision.
