print/cups-base web interface broken & unable to print

[Karel Miklav]

For the record: I was using different HP inkjet printers with
FreeBSD for years, but printing via CUPS/hpijs stopped working
couple of months ago. Scanning via XSane still works though.

I did some pkg upgrades and "portmaster cups hplip sane",
checked the regular suspects; device permissons, compiled USB
drivers etc, but have no more time to invest into this. I
print from some other operating system hosted in VirtualBox.

Karel
