Comment 45 for bug 998156

Jan, thank you for the tests. Firefox has sent the "PageSize=Custom.Custom...." in both job 445 and 446, the difference is that the filter chain for the HP driver breaks on it but the filter chain for cups-pdf not. Evince does not send the broken PageSize attribute and therefore prints correctly.

This means that the bug is either in Firefox or GTK.

CUPS and the drivers are OK. They do not need to accept "PageSize=Custom.Custom....".
