<p>In the US, I am finding that the HP 1010 (HP 61 and 61c inks) and Canon Mg2520 (pg-245 and cl-246) are cheap and plentiful.</p>
<p>Supposedly HP still has its developer program – but I think the NDAs may not work out. Canon is usually better about comprehensive service manuals – my early canon bubblejet has complete schematics of the printhead…. Mounted in what appears to be ABS.</p>
<p>Hopefully we can find a service manual for a Canon model that uses those cartridges.</p>
