I logged in as the user and checked the default paper for the printers and it remains A4. I wonder if CUPS (if it is involved in this process), is doing a live query of the printer via IPP (or other) and the printer itself is configured to default to A4 paper? Something like: $ ipptool -tv -I ipp://cups-server/printers/branch ./get-media.ipp "./get-media.ipp": Get-Printer-Attributes: attributes-charset (charset) = utf-8 attributes-natural-language (naturalLanguage) = en printer-uri (uri) = ipp://cups-server.rap.ucar.edu:631/printers/branch requested-attributes (keyword) = media-default ./get-media [PASS] RECEIVED: 109 bytes in response status-code = successful-ok (successful-ok) attributes-charset (charset) = utf-8 attributes-natural-language (naturalLanguage) = en media-default (keyword) = na_letter_8.5x11in you might use 'localhost' or try the printer directly with a URI like ipp://printer-ip/ipp or ipp://printer-ip/ipp/port1 (many laserjets). $ cat get-media.ipp { OPERATION Get-Printer-Attributes GROUP operation-attributes-tag ATTR charset attributes-charset utf-8 ATTR language attributes-natural-language en ATTR uri printer-uri $uri ATTR keyword requested-attributes media-default } --stephen
