I'm programming with OS/2 EE using Presentation Manager (PM) and Database Manager (DM). I'm developing a graphical system using lot of Gpi-calls in the PM. In connection to that I use the HP7550A plotter driver. I first draw a graph in a presentation space associated to the screen on my PS. Then I reassociate the presentation space to a plotter device (HP7550A) and plott the graph. The HP7550A plotter dirver that was in version 1.1 of OS/2 had lot of errors, for example polymarkers where scaled to world coordinates and there was no font that were usable in small scale except the system font. So I had to inverse transform all polymarkers to get the correct size before plotting. And I had to text all my plotts with only the system font that was not cabable of any of the special Icelandic characters. Therefore it was good news for me when I heard that version 1.2 of OS/2 EE included much better plotter drivers. So I upgraded my operating system to version 1.2 (the toolkit also). And what did I get? It seems to me that the new plotter driver is much worse than the old one. It is not capable to draw the before mentioned system font. Instead it supports 25 outline fonts that are not usable at small scale at all. I only get a blottesque when I try to use those fonts at normal size. Therefore I can't text my plotts at all those days. That is quite annoying because I know from a MicroVax HP7550A driver it is possible to get lot of fine fixed size fonts. I have tried to solve this problem by innstalling the version 1.1 driver again. But the font problem still exists. There is lot of other problems with that plotter driver that I will not mention here but will be quite sattisfied if somone can solve the font problem. 1) Are ther any fixed size font that I can access through the HP7550A driver? If not is there any outline font that is usable at small scale (small font)? 2) I will finally mention that I have not seen any special documentation for the HP7550A driver (it's capabilitys etc.). Does it exist? If so, where can I get it? 3) Does there exist any other plotter driver (for HP7550A) that works? Please reply by e-mail and I'll summarize on the net if there is enugh interest.
