Upgrade from 3.12.6 to 3.12.11 changes `DefaultImageableArea` and `DefaultPaperDimension`

[Paul Menzel]

Using Debian Sid/unstable upgrading the package `hplip` from 3.12.6 to 3.12.11 from experimental, the following changes were applied to `/etc/cups/ppd/Photosmart_2600.ppd`.

diff --git a/cups/ppd/Photosmart_2600.ppd b/cups/ppd/Photosmart_2600.ppd
index 881493b..dd3c7a4 100644
--- a/cups/ppd/Photosmart_2600.ppd
+++ b/cups/ppd/Photosmart_2600.ppd

-*UIConstraints: *OptionDuplex False *Duplex

-*DefaultImageableArea: A4
+*DefaultImageableArea: Letter.SM

-*DefaultPaperDimension: A4
+*DefaultPaperDimension: Letter.SM

What are the reasons for and consequences of these changes?

Hi Paul,

Photo smart 2600 PPD has been updated for Duplex options only and default paper size is not updated in hplip-3.12.11.
Please find the below diff between hplip-3.12.6 and 3.12.11 versions.

Reason for removing Duplex constraints is, currently HPLIP package is not querying dynamically duplex unit information.
If user has duplex unit and Duplex constraints are present, user can see the option after updating the duplex unit information through CUPS. Many user may not be knowing this information so PPD updated to show duplex option information always.
