royal<p>Edit: I installed drivers from the Brother website. Can you believe it? Much better results. The printer was functional before, but much better quality now. </p> <p><a href="https://theres.life/tags/cups" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cups</span></a> help please.</p><p>My printer insists on printing at 300dpi, and I know it's capable of higher.</p><p>I don't see any UI choice to change this (PopOS, KDE Plasma). I do see 300 listed in the PPD files. If I change (say) the DefaultResolution line from 300 to 600 and restart cups, it appears to regenerate the file clobbering my changes.</p><p>How do I force this to print at a higher resolution?</p><pre><code>Brother_MFC_J6945DW.ppd:*DefaultResolution: 300dpi<br>Brother_MFC_J6945DW.ppd:*cupsPrintQuality Normal/Normal: "<</HWResolution[300 300]>>setpagedevice"<br>Brother_MFC_J6945DW.ppd:*cupsPrintQuality High/High: "<</HWResolution[300 300]>>setpagedevice"<br></code></pre><p><a href="https://theres.life/tags/linuxDesktop" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linuxDesktop</span></a> <a href="https://theres.life/tags/linuxHelp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linuxHelp</span></a> <a href="https://theres.life/tags/linuxPrinting" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linuxPrinting</span></a> <a href="https://theres.life/tags/printing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>printing</span></a> <a href="https://theres.life/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linux</span></a></p>
