re laserjet iv upgrades to dpi opinions larryhow austin ibm com wrote what are the current products available to upgrade the resolution which ones support postscript any experiences with them either good or bad is the quality difference really noticable i m planning on producing camera ready copy of homes will the higher resolution be noticed for these if you are talking about laser jet then i believe it has to be postscript i don t see any advantage to using pcl when you have a peice of hardware plugged into the lj that is doing the work and it can support any language that is suited for the job besides i don t think pcl is even capable of handling dpi specifications i only have experience with the laser master winjet which brings the lj up to dpi and it uses postscript it also has a fast print mode which is not postscript and it is at a lower resolution dpi i think but it is fast this particular product uses your host processor to process the postscript so even with a decent pc you know it s going to be slow i e slow compared to a high end workstation processed ps the quality difference is very noticable and is almost worth the wait for the ps processing i m rather impatient we were using it for b w camera images rs the gray scale image was accepted by ms word and handed to the winjet ps printer driver which converts the image into postscript and then hands it off to the winjets postscript processor the postscript is rendered into ram lots of it and when it is done it shoots it directly to the printer the ps processor can also accept ps files created from other sources including dos applications but windows has to be running at the time of printing the ps processor is responsible for the halftoning and i d say it does a pretty good job our camera images came out very good in my opinion not as good as laser master s demo though i don t know how many other similar products are out there but i would be surprised if there are several gordon lang
