Re: [Gimp-print-devel] Mitsubishi CP-D70DW Problems

[Felix H. <fh...@wa...>]

Hi Solomon,
Thanks for your quick response, I installed cups-filters now, works now with the extra line in the conf file but now cups takes about a minute to print it, before it was not even a second, any ideas on how to speed that up?
You have a Buy me a beer button somewhere? :-) Cant describe how great it is to have it working after such a long time

thanks
felix

Now I bought an Mitsubishi CP-D70DW and got it working on a RPi4 with
Cups and the plugin from http://www.peachyphotos.com but i don’t know
how to set the driver to not change the proportions when I print with
AirPrint using an iPhone.

The short version is that CUPS does not properly support being an
AirPrint server, and they have no plans to change that.

All the Pictures will be fit to 4x6 but not being zoomed in but expand
the corners to the paper size.

I don't know what version of cups-filtes that's running on your RPi4,
but cups-filters 1.22.2 or newer has much-improved scaling options that
should do what you want.

I think you'll want the 'print-scaling=fill' option, and on the cmdline
you should be able to set it as default:

lpadmin -d queuename -o print-scaling-default=fill

(Alteratively, stop cups, edit /etc/cups/printers.conf and within the
block for the printer, add a line that reads 'Option print-scaling fill')

Any idea on how to solve that? When I edit the picture on the iPhone
first and crop it to a 2:3 format it works just fine but can’t this be
done with the driver? I can set the Shrink Page if necessary to fit
borders to any setting, the result is always the same. Is it just that
the AirPrint does not send the available paper size? Could that be?
With my other printer where AirPrint works OOB i can set all the paper
size etc. within the AirPrint setting.

It's not exactly an ideal situation, but other folks I've talked to end
up creating multiple CUPS queues for the same printer, but with
different page size options, and select between them with AirPrint.
