Two different model HP printers in two locations. Each one will allow me to remotely print a photo from my phone (a new model Samsung), but never a document from my phone: documents come out as blank pages, even though the print preview shows document in the configuration I want. Printing and copying from the PC works well. Finally was able to configure printer for scanning for a crucial project, but only after initially finding out that printer was not yet configured for scanning after being told it was. Tech support with a human is unreachable. Automated support is moronic at best.
