I have 2 computers in my shop, one runs Windows 98 the other Windows XP. They each have their own HP 5000's and are connected to a Cannon 3200 equipped with a Fiery controller over a network. The Postscript that is generated on the XP for the HP 5000 doesn't have an 04hex terminating byte so the HP prints but keeps on looking for more data and eventually generates a timeout error. When I send a job to the Canon in landscape format the paper orientation seems to be correct (judging from the Fiery software preview screen) but the text or graphic on the page is still in portrait mode. On the Windows 98 machine I don't have any of these problems.
I should mention that Pagemaker output works fine on both machines. Unfortunately, 99% of our output is generated with Corel products.
What I would like to know is can I get rid of the PSCRIPT5.DLL driver on the XP machine and substitute the ADOBEPS4.DRV which is working fine on the 98 machine. If so, how do I go about it?
Thanks,
Jerry Taylor
