Print management for macOS users with PaperCut NG. PaperCut NG is also architected to take advantage of multi-processor systems making it. The first place to start is the installation guide. I also want to track printing, scanning and copying on copiers and MFDs. I am a long-time Mac user and have a suggestion? Nov 2, 2016 - If you still can't open the printers list in Safe Mode, temporarily move the. Did not work here, same as @will. After a long while (about 3-4 minutes in my case) the printer preferences. Then, right-click in the printer list, and select Reset printing system. Not the answer you're looking for? 8 months ago.
Recently my office has been having some problems with our network printer. Four computers and the printer are connected to a switch. All four of them can print documents.
There is no router or internet connection. However, two of the computers often take a very long time to send the information to be printed to the printer. Sometimes they can't even detect the printer giving error messages, and many, many minutes later the printer will print the document. The other two computers seem to be able to print almost straight away all the time. We installed the printer drivers the same way on all the machines. That is by inserting the CD, letting the computer detect the printer, and then clicking continue until it's done. Checking the printer network settings (from the printer menu) shows the following (if it helps):.
IP address 169.254.179.195. Subnet 255.255.255.0. Gateway 169.254.179.195 What is the most likely cause for the error? If there's no server or router or Internet connection, it should be fine to leave your network using IPv4 link-local addressing (self-assigned 169.254.x.x addresses).
I'm guessing you're having speed problems from two machines because of basic Ethernet problems. Maybe the cables runs from those offices to the switch are too long. Or maybe the RJ-45 plugs weren't crimped onto the cables correctly. I'd try swapping the cable/port that one of the 'slow printing' computers is connected to, with the cable/port one of the 'fast printing' computers is connecting to, to see if the problem follows the machine, or follows the cable and port. If the problem follows the machine, I'd look at the Ethernet speed and duplex settings for that machine, and make sure you don't have a speed/duplex mismatch between that machine and the switch.
You might discover something silly, like maybe the two 'fast printing' computers and the printer only have 10/100 Ethernet cards in them, but the 'slow printing' computers have 10/100/1000 cards, and maybe your switch is too cheap and isn't handling flow control well, so it's dropping lots of packets from the two Gigabit Ethernet machines, but the traffic from the two 10/100 machines doesn't overload the printer port, so that traffic doesn't get dropped. Printer's IP address is link-local address that is assigned by default if there is no DHCP server in network.
The printer and computers have to be in the same subnet in your case. You should check one of the computer's network settings and assign it to the printer but don't forget to change the IP address. E.g: If computer's setting is something like this: IP: 192.168.1.5 Subnet Mask: 255.255.255.0 (no default gateway if there is no router) then your printer's should be like this: IP: 192.168.1.(something other then the PCs) Subnet Mask: 255.255.255.0.
Answer The Apple specs say the MacBook Air 2012 supports up to 2560 x 1600 on an external display. The LG UltraFine 5K manual says it has a 2560 x 1440 at 60 Hz timing so it should work but maybe not. The Macbook Air (13-inch, Mid 2012) only has Thunderbolt 1 (10 Gbps). 2560x1440 60Hz uses about 5.3 Gbps, which leaves less than 5 Gbps for all the USB devices of the LG UltraFine 5K.
But Thunderbolt 1 has two bidirectional 10 Gbps channels. If the display uses one channel, then the other channel is free for USB devices.
I guess the only way to know for sure is to try it. To get 5K though, you need an eGPU with Thunderbolt 3 output. The only solution so far is the Blackmagic eGPU (all other eGPU's do not output their DisplayPort signals through a Thunderbolt 3 controller). Apple does not support eGPUs on Thunderbolt 1 or Thunderbolt 2 Macs, so you'll need to use a workaround (available on the eGPU.io website). Answered by Joseph V from Fort Langley.
Jul 26, 2018. The LG UltraFine 5K Display is a Thunderbolt 3 display which uses both DisplayPort connections of the computer's Thunderbolt controller.
The Thunderbolt controller sends both DisplayPort signals to the Thunderbolt controller of the LG UltraFine 5K over the Thunderbolt cable. The Thunderbolt controller in the LG UltraFine 5K converts both Thunderbolt DisplayPort streams back into DisplayPort to be used by each half of the display (the left and right sides) to support 5K resolution.
That is also the reason why the LG 5K display does not have a second Thunderbolt 3 port - because it is required for one of the DisplayPort signals for one half of the display. The other DisplayPort signal comes out of a DisplayPort connection of the Thunderbolt controller of the display (think of a Thunderbolt 3 dock where you can connect one display to the second Thunderbolt 3 port of the dock, and another display to a DisplayPort output of the dock). The Thunderbolt controller of the computer does not have a third DisplayPort connection, and since the LG 5K uses two DisplayPort connections (over Thunderbolt), an LG 4K display cannot be daisy chained to the LG 5K display.
Also, since a Thunderbolt controller only has two DisplayPort connections, if you connect a LG 5K to one side of the MacBook Pro, then a second display must be connected to the other side of the MacBook Pro (there's one Thunderbolt controller per side of the MacBook Pro). One 5K or two 4K per side of the MacBook Pro can be connected. The USB-C ports of the LG UltraFine 5K only support USB. They do not support DisplayPort because there is no other DisplayPort signal on the Thunderbolt cable that can be used and the display has no other DisplayPort inputs. It might be possible to use a USB to DisplayPort converter (research devices that use DisplayLink, find examples at the DisplayLink or plugable websites) but they don't perform like real displays and may have issues in macOS.
