Help modifying HP PPD

[Tom Rymes]

Folks, due to the fact that the PPDs for my HP P4014 and 4250 printers are rejected by CUPS and cupstestppd, I am in the process of modifying those files to make CUPS happy. I'm running CentOS 4.7 with CUPS 1.2.12, and I tired HPLIP, but it seems a whole lot more cumbersome than making the PPDs work.

Anyhow, I have changed all of the lines that were causing problems because the main keyword was over 40 characters when the "Default" was added to it, so now I am fixing all of the options that do not have a default defined. (In the archives, I found reference to info saying that "Default<main keyword>" should be accepted by CUPS, but that that causes problems for localization, etc. Has this changed?)

Here is a sample section. What should I set "DefaultHPInstallableTraySize" to? I don't want to accidentally find that I have set the default to something other than "Printer Default" or something similar. Has anyone produced an edited PPD that passes cupstestppd?
