I have successfully updated the software on the HP 15000 printer, which I previously downloaded from your site. But now the problem is that this software - the driver does not support printing in A3 or A3+ format. Are you aware of this problem?.. This question was asked earlier on the forum - but you still did not answer the essence of the problem. Your chipless firmware, posted on the site after installation, does not support printing in A3 and A3+ format... for the HP 15000 printer.
