Canon i950 printing is faint with Leopard
The printer is connected via USB to a Linux server at home running Turboprint and networked using CUPS. The printer has been working 100% with 10.4.11, no problems, always nice and dark printing.
After doing the "BrowseProtocols all" CUPS fix in Leopard, the printer has been working but printing very faintly compared to Tiger.
Yes - I've checked the ink levels!
The printer output is still nice and dark when I print from my old Mac (Tiger 10.4.11) so I know it's not the printer or the server, it's got to be something different with Leopard - but I can't figure out what.
There is no new Canon i950 printer driver available from Canon, their website says that the driver is built into 10.5.x which is fair enough, but their appears to be a problem.
There isn't a ColorSync profile for the printer either - could that be a problem?
Finally, I've tested printing on a Macbook running 10.5.2 and it also is printing faintly so I am convinced that the problem is inherent to Leopard, since I don't have any problems with faint printing with Tiger.
Any pointers on how to fix this or where to look?
