Hi Till,
My gut response is remove the script.
However this may bring into play problems with jobs sticking in the
queue for no apparent reason that I mentioned in the original bug post.
This definitely occurs when printing from applications using gtk+ and is
caused by cups not picking up that GS has terminated with an error, in
this case "rangecheck in SetPageDevice. This error is only reported in
the error_log if debug logging is enabled. I think it would be a good
idea to fix this anyway!
I have been looking at a solution using cupsUIConstraint and
cupsUIResolver to forbid the use of non duplex page sizes when duplex
printing is selected and a .duplex page size is available. I have not
got it to work yet.
The idea is to insert lines like these after each .Duplex CustomMedia found.
Attribute cupsUIContraints A4Pagesize "*Duplex *PageSize A4"
Attribute cupsUIResolver A4PageSize "*Duplex *PageSize
A4.Duplex"
Attribute cupsUIContraints A4PageRegion "*Duplex
*PageRegion A4"
Attribute cupsUIResolver A4PageRegion "*Duplex *PageRegion
A4.Duplex"
Attribute cupsUIContraints A4ImageableArea "*Duplex
*ImageableArea A4"
Attribute cupsUIResolver A4ImageableArea "*Duplex
*ImageableArea A4.Duplex"
Attribute cupsUIContraints A4PaperDimension "*Duplex
*PaperDimension A4"
Attribute cupsUIResolver A4PaperDimension "*Duplex
*PaperDimension A4.Duplex"
