Bought a new HP Smart Tank Wireless 515, still same issue about ipp-client-kotlin HOT 2 CLOSED

I can't see where HPs hardware spec mentions PDF. According to the printer attributes PDF is not supported:

document-format-supported (1setOf mimeMediaType) = application/vnd.hp-PCL,image/jpeg,image/urf,image/pwg-raster,application/PCLm,application/octet-stream

However you can try to render PDF to PWG as mentioned in issue #2.

This library implements the IPP network protocol. So you have to provide a document in a format the printer supports. Once you have produced printable data you can then submit (=print) the data/document to the printer via ipp.

(In case a software spec for a printer driver supports PDF you'd also have to use this software to use it's features)

from ipp-client-kotlin.

@gmuth Actually i had a workaround because i had another raspberry pi laying around and use that as a CUPs print server which has more capabilities and that different printer manufacturers support things at their whims.

PDF to PWG is too hacky as i've tried that route before as javax.* libraries are not supported by Android since Android uses different libraries to render.
