README says to use textonly.ppd which doesn't exist

[alexhenrie]

Describe the bug
Under "TEXTTOTEXT", the README says:

In the printer setup tool select the "Generic Text-Only Printer" (with lpadmin use "-m drv:///cupsfilters.drv/textonly.ppd")

When I follow the instructions and run lpadmin -p textonly -m drv:///cupsfilters.drv/textonly.ppd, I get:

lpadmin: cups-driverd failed to get PPD file - see error_log for details.

Expected behavior
There should be clear instructions on how to use the TEXTTOTEXT filter, including instructions on how to get any required PPD files.

Additional context
textonly.ppd was deleted in commit 651ec22 ("texttotext, textonly: Replaced script-based textonly by more versatile C-based texttotext filter.", 2016-07-14).

A Google search turned up at least four other people looking for this file:

• Where did the textonly.ppd file go in RHEL 7?
• ppd textonly missing
• Need to enable CRLF on old line printer connected to RHEL
• Dot Matrix Printer Support
