For a discovered printer,information that has been changed is reset after reboot.

[Richard Olsen]

So I did a lot of changing and cutting and pasting and rebooting and didn't learn much of anything.  I then decided to edit files printers.confg.O and printers.confg.  In each of the files I deleted everything related to the color printer and the fax, but left the stuff for the parallel connected printer and the PDF printer, and then I rebooted.

After the reboot, in file printers.confg.O what I had left there was still there plus information for the color printer (but not the fax).  The first few records for the color printer were:

<DefaultPrinter HP-Color-LaserJet-CM1312nfi-MFP>
Info Hewlett-Packard HP Color LaserJet CM1312nfi MFP
Location gwp3
MakeModel HP Color LaserJet cm1312nfi MFP hpijs pcl3, 3.10.2
DeviceURI hp:/usb/HP_Color_LaserJet_CM1312nfi_MFP?serial=00CND896S5L2

In the printers.confg file was the stuff I had left plus information for the color printer and the fax.  The first few records for the color printer were:

<Printer HP_Color_LaserJet_CM1312nfi_MFP>
Info Automatically setup by HPLIP
Location
MakeModel HP Color LaserJet CM1312 MFP Series Postscript (recommended)
DeviceURI hp:/usb/HP_Color_LaserJet_CM1312nfi_MFP?serial=00CND896S5L2

Notice that the only thing in common between the two snippets is DeviceURI.  So do you suppose that both files were set up properly by CUPS and then HPLIP modified (incorrectly) printers.confg??  If so, then changes will always be lost after a reboot.

If I change some of this information, such as printer name, location, device driver, etc., the changed information is lost when I reboot the system. It seems to me that this information should be retained on reboot. In fact, on an earlier release of cups/hplip and an earlier operating system, those changes were preserved.
