[DeskJet 812C] hp-align not working

Asked by Aaron Albright

I'm using an HP DeskJet 812C connected to the parallel port of a Debian
GNU/Linux machine with cupsys 1.2.1-4, hpijs 2.1.10+0.9, and hplip 0.9.11-2.
All packages are binaries from the Debian repository.

The printer has been successfully installed using the hp:/ backend, and the
device URI in CUPS is hp:/par/DESKJET_810C?device=/dev/parport0. The
built-in test page works, and CUPS can produce its test page -- however, all
printouts are unreadable due to what I presume are cartridge alignment
issues.

If I attempt to run hp-align, I get the following:

 0001 # hp-align

This should be fixed in the next release. However here is a workaround:

su
cd /usr/share/hplip/data/xml
gedit models.xml

Locate this section:

<model name="DESKJET_815C">
    <id></id>
    <icon>DESKJET_840C.png</icon>
    <support type="2"/>
    <case-model>
        <model1>Deskjet 815c</model1>
    </case-model>
    <io support="1" mode="0" control="0" mfp-mode="2" scan-port="0"/>
    <align type="2"/>
    <clean type="1"/>
    <color-cal type="0"/>
    <status type="1" battery-check="0" dynamic-counters="0"/>
    <scan type="0"/>
    <fax type="0"/>
    <pcard type="0"/>
    <copy type="0"/>
    <tech class="DJ8xx" type="2"/>
    <embedded-server type="0"/>
    <panel-check type="0"/>
    <linefeed-cal type="0"/>
    <pq-diag type="0"/>
    <r0>
        <agent1 kind="3" type="1" sku="15 (C6615DN)"/>
        <agent2 kind="3" type="2" sku="23 (C1823D)"/>
    </r0>
</model>

Change:

    <io support="1" mode="0" control="0" mfp-mode="2" scan-port="0"/>

TO:

    <io support="1" mode="1" control="0" mfp-mode="2" scan-port="0"/>

Save, Exit, restart HPLIP (/etc/init.d/hplip restart)

hp-align should work.

We are looking into a long term solution as well.

Let me know if you have any problems.

Aaron
