The Hewlett Packard (HP) Sendfax command is part of the hp-toolbox command; it may also be invoked separately as
hp-sendfax. The dialog windows that open at invocation are the same. I tried both variants and encountered the same error messages.
I can wite a letter with Libreoffice. If I like so send it by fax, I could print it and fax it from my HP All-in-one printer. In order to avoid the print-out, I exported my letter to a pdf file and tried to send it with the hp-sendfax command.
To do so I open a terminal window in the folder where my pdf-letter sits. I invoke hp-sendfax. A sequence of dialog windows appears, where I specifiy the pdf file to send and the recipient’s fax number, e.g. xxxxxxxxx (in Germany).
Finally I click the send fax button. An error appears in the last window of the hp-sendfax command and, after I close it, I see the following messages in the terminal window:
error: Unable to acquire fax token (3).
error: Fax send error.
error: Error, aborting.
I posted that problem in the HP support forum - no answer. Therefore I am trying to obtain support in the Manjaro forum. Would be great if someone could help!
