Printing on HP T230

[BGunn64]

Here's the scoop...
Work at a sign shop and we've been printing on 24" HP printers for a long time now - they are great for edit tapes, drill templates and various assembly templates.
These templates vary in length and I usually end up taking the overall length of the image and adding 3" so it won't distort. We run strictly B&W in vector (lines) format.
We started out with an HP DesignJet 430, added an HP DesignJet 450 until both units were no longer repairable at which point we bought an HP DesignJet T-120.
Now that one is having some issues and so we bought the HP DesignJet T-230.
We are printing directly out of our sign program and, for the most part, have had no problems until the print drivers update.
The 430 & 450 print driver were great as they required the least amount of change to the settings when sending out a print.
The T120 takes a few additional steps but still is workable as long as I use the PCL Type 3 driver. When I reset my system last fall, and I forgot which driver to use, it caught me by surprise when the newer driver installed. It just does not allow for easy changes to the length settings. {I was able to drop it back down}
Now that we have the T230, I am trying to get that to run with the same driver and not having much luck.
The PCL Type 4 driver does not allow me to change the length easily without generating a whole new print profile (if you know what I mean).
Looking for some input and insight in getting this newer printer to perform like we are use to.
Looking forward to hearing any suggestions that someone might have in helping me out.
Thanks.
