Hello, my name is Dan.
My home is close to Lake Ontario in New York State in the Eastern time zone, I am generally online between 10 AM and 11 PM Eastern standard Time.
You say 'Macs' as in multiple, please tell me what version of OS X is on each and what type they are?
How and to what is the printer connected?
I have three Mac's, two iMac's and one Mac Mini and four PC's. The Mac's are all on 10.8.3. Konica doesn't support the age of the machine we have Bizhub 351c.
It is connected by a network using an ip address.
I had originally found a small work around program and they all worked. The printer went off the network and when we got it back on the Mac's wouldn't print anymore. I don't have the work around program anymore.
I found that software already. I have downloaded it several times and installed it but I don't think the new driver is getting to the printer. I uninstalled the printer and reinstalled it as well and I can't seem to get it to use the new software I downloaded.
Printer addition 10.6, 10.7
That didn't work either and it wiped out my other printer.
I did finally get the new driver installed and I still can't print.
Use these steps to add the printer. If the other printers worked before resetting they will work again after re-adding them.
The same should be true for the Minolta but it may be stubborn.
Also this will go a long way to fix this and other issues you may not be aware of.
I check and repair permissions regularly. However I followed your directions and it doesn't print. I removed the printer, reinstalled it and repaired permissions again and it still won't print.
No messages. When I install a new printer it lets me select the new driver I downloaded. That driver appears on the printer settings. I also tried installing the printer using its IP address and it doesn't see the printer.
