There is perhaps a bug in the Document viewer or the GTK print dialog,
sending an incorrect option for the custom paper size. It has to send
"PageSize=Custom.<width>x<length><unit>", with <width> being replaced by
the width of the paper, <length> by the length, and <unit> by the unit
in which the width and the length are expressed ("in", "cm", "mm",
"pt"). If the unit is omitted the default unit "pt" (PostScript points,
1/72 inch) is used.

There were already reports that "PageSize=Custom" or
"PageSize=Custom.Custom.<width>x<length><unit>" got sent.

Please follow the instructions of the section "CUPS error_log" on
https://wiki.ubuntu.com/DebuggingPrintingProblems and see in the
error_log what gets actually sent.
