Quite interesting, thanks. And it seems to confirm that the GDI printers have quite limited capabilities.

>>>Not trivially; there are no 'printer codes' per se in the GDI printers, since they have no internal rendering engine to address. Your best bet in the short run is going to be to purchase a commercial version of GhostScript (a PostScript emulator that works through the GDI) and send PostScript to the printers; GhostScript will intercept the PostScript codes and render the page through the GDI. This means that you'll have to support PostScript through your ??/@ reports - there's at least one commercial GhostScript implementation that supports PCL and Epson LX codes as well as PostScript, but it's going to run ~ $100/station, about what a real printer would cost. I'm not certain you'll be saving time or money - you're likely to find that the cost of 'real' printers to replace the GDI crap is going to be less than the cost of implementing GhostScript or converting your reports.
