One feature you may run into by forcing pages to "A" size is that PTC postscript generation scales the vectors, but not the line widths.
For stroked text, if the text is to be .010 line thickness and .156 high, then it will still be .010 line thickness when scaled to, say, .030 high. All other graphics get the same treatment.
As of WF5, setlinecap and setlinejoin still have poorly chosen values. The values for both of them should be 1.
To counter the line width problem you can create .pnt files for each original size and scale the pen widths correctly, or create a pen table that has a tiny pen width no matter what the scaling.
You can also edit a Postscript file that is printed to its original size and scale it correctly there.
To try this, edit the ps file (notepad or wordpad or other non-layout text editor) and, after the line 72 72 scale add a new line like 8.5 44 div dup scale. This divides the target size (8.5) by the original size (44), the duplicates that value and then scales the remaining drawing commands.The first 72 is the X scale, the second is the Y scale and Postscript doesn't care if they are not the same number, but you might not like the printed result.
The line near the top, <</pagesize[>> setpagedevice tells the printer what paper to expect. If your printer only handles A size, then clip out the lines from "systemdict" to ") if." It's a hint to the printer, but not required.
