It appears that the 1.6.x releases of CUPS print worse on my line
printer.

This is simply background information as I haven't had a printer in
several years, but I've been reading about it in my various FLOSS-related
news feeds.  In case you didn't know, Apple, who bought out the folks
formerly sponsoring cups and its developers, has *SERIOUSLY* (and
extremely controversially) changed it recently (for 1.6 IIRC), basically
ignoring the Linux use case and dropping the former support for it,
resulting in huge problems on the Linux side.

Yes, now LFS/BLFS had gotten it to work. The problem is that the RIP doesn't work correctly.

A project to take up the slack and continue maintenance and development
of the filters and other cups infrastructure for the Linux side was
established and is now sponsored by the Linux Foundation which should
take care of the problem going forward, but the transition hasn't been
exactly smooth, to put it mildly.

I can only hope that they would fork it and fix what I believe are serious design errors.

It needs to use an unmodified PPD files to describe the printer. There should be a GUI program to edit and generate PPD files.

It needs to have separate configuration files for each printer to choose the RIP that is used. The configuration files should be edited by the GUI interface.

If Ghostscript is chosen for the RIP, that should mean that the Ghostscript "drivers" could be used to print with or to generate files.

The idea of using a universal RIP and then converting the raster image that it generates to match a printer is simply NOT a good idea. It should be scraped.

There should be a CUPS lite subset for people that only want to use printers directly connected to their computer.

So either expect and be prepared to deal with and work around hopefully
temporary printing issues such as yours until everything settles down, or
if possible, consider staying with older working cups for another year or
so, /then/ upgrade, after everything has hopefully settled down and works
once again.

I guess that the only possibility is to see if I can get Foomatic to work. I think that I can setup direct printing with OpenOffice, but Qt/KDE will only print with CUPS -- very bad idea. Not having a simple print spooler for PS application output as part of KDE is also a poor choice.
