To print to HCP from an PC client running Linux one uses the OS printer management tool or CUPS and create an  IPP or better IPPS printer, with following options:

• URL : ipps://<hcp-hostname>:9631/ipp/<printer-name or printer-ID>/accountdomain=<hcp-domain-fqdn>/username=<user-name>/providerid=<auth-provider-ID>

• When asked for the printer model, use the EveryonePrint Universal Driver PPD file attached below.

Explanation:

• You can use either printer name or printer ID that you see in printer settings in HCP
• Provider ID is the ID number you see for ex in settings of the LDAP Authentication provider
• For IPPS you need to have a trusted Certificate

Here an example:

ipp://appliance-01.acme.com:8631/ipp/2/accountdomain=print.acme.com/username=user1/providerid=6

It's possible to use the 'lpadmin' Linux command in a script to automate installation... tons of examples are available online.
