- I'm working on a program which uses PPD files and to test it I grabbed
- a bunch of PPDs off the Adobe file server. I have run into some weird
- things in PPD files and was wondering if anyone else had run into similar
- problems and what you decided to do about them:
-
- 1) Why do the Lino PPDs for PostScript versions < 52.3 have entries
- for *SetResolution, but versions > 52.3 do not have entries for
- *SetResolution? We have a RIP 30 with 52.3 and I'm pretty sure
- you can change the resolution if you do an exitserver first.
-
- 2) The entries under *ScreenProc seem pretty useless, especially if
- the device has a screen filter installed. There is a special PPD for
- an AGFA SelectSet 5000 with the screen filter active, but RoundAGFASpot
- and EllipticalAGFASpot (or whatever they are called) not listed under
- ScreenProc. It would be very useful if they were.
-
- 3) According to the PPD spec, the value following *MaxMediaWidth is an
- integer inside double quotes. I got L3330523.PPD and L530_523.PPD
- off the Adobe file server and the numbers after *MaxMediaWidth were
- not inside double quotes.
-
- 4) None of the PPDs for the Varityper imagesetters have a *CustomPageSize
- entry. From looking at the file it seems you could use the setpage
- operator almost the same way as setpageparams on most other RIPs?
- I could swear that I used a Varityper imagesetter once and it supported
- the setpageparams operator.
-
- 5) One of the Varityper PPDs has the wrong invocations to set the
- resolution to 1270. It actually tries to do "270 setresolution".
- Of course, there could be some really weird bug where you have to
- say "270" instead of "1270", but I doubt it.
-
-
- Actually, if you've ever done anything at all with PPD files I'm interested
- in hearing about it.
