Canon 8580cdw Prints documents, but not well from a web page

[BluelimeGraFX]

The last time I changed toner cartridges out I can print from Illustrator or any document program with no issues, but when it comes to printing from email or an invoice from Quickbooks online then it is spuradic in printing.  Some times it will be fine and you can see al the print.  Other times it prints certain parts of the document, but other parts ar light and hard to read or just blank with nothing printed.  I tried printing out an email for two days now and all the email chain prints okay EXCEPT the latest email in the chain.  That part is completely blank except the header info.  I copied and pasted the text into Adobe Illustrator and it prints just fine.  I can't be doing that every time I have to print an email chain for a job I am working on or downloading PDF's of the invoices just to print them out.

What is the issue with this and how can I fix it?

Some of those files you said to delete are not named the same as you gave me....

UFR2 or MF..... not there - I have..... CUPS_MF_Printer and CUPSFAX and CUPSPSMF and IJScanner and MFScanner

jp.co.canon.UFR2.BG.plist..... not there....I have.......jp.co.canon.ScanGearMF.appl.Canon-MF-Scan-Agent.plist and jp.co.canon.ScanGearMF.appl.Canon-MFSU-Agent.plist

CNTD***Z*2*.ppd.gz... not there....I have......CNMCMF6100FB.ppd.gz among others under CNMCMF as well as CNPZBD500ZB.ppd.gz and CNPZBMF110ZB.ppd.gz among others under the CNPZ...Do I just delete all the 8500ZB or all of them including the 500, 6100, 8000, 8200, 6800 and so on?  I have another printer that I am afraid will break that printer if I delete the wrong files.

Hi BluelimeGraFX.

If you don't see any of the other files, that is fine. You only need to delete the 8500zb file. Once it is deleted, restart the computer, and then empty the Trash.
