has anyone had any trouble connecting to a router, and does it work great from router or does your router fry

I have these on networks with a Netgear FVS 336G router and a Cisco RV345P and they work fine. The IoGear manual is obsolete an so the instructions are fairly useless, so see my answers to other questions here for details on configuring.

Is it compatible with DYMO label printers (400, 450)?

I'm using this on a network with Macs and PCs running Mac OS Sierra 10.12.6 and Windows 7 pro and Windows 10. All work fine, but getting the print server configured with a static IP address was a pain on the Macs, only due to the poor documentation, therefore some tips below. TIPS FOR CONFIGURING (MACS AND PCS) Note for the instructions below, the print server should be connected to your network and powered on. The user manual doesn’t go into enough detail on how to properly configure. The print server uses DHCP (from your router or cable modem) to assign it a network IP address. The problem with this is, that address is not fixed and can change, and then your printing stops working. So you need to configure the server to have a static (fixed) IP address. To determine what address to set it to, once you have the print server connected to your network and powered on, your router or cable modem will assign it a random IP address. You can then check your router or modem configuration to find the assigned address; somewhere in the config settings you’ll find the IP address. (If this is too technical for you, get a techie to do this.) You can change the print server config to make that IP address fixed. On a PC this is fairly easy, you just follow the instructions for setting a fixed IP address during installation, an enter the device’s current IP address. On Macs, there is no IOGear installer, so you must first configure the static IP address of the device in a browser by entering the device’s current IP address that you got from the router or modem config into a browser. That will bring up the print server’s config page. Click on the “TCP/IP” link and change the TCP/IP setting from “Automatic” to “Manual:” then you can then enter the fixed IP address. The subnet mask and gateway address should already be there, but if not, you can get it from your router or Mac OS network control panel (Apple Menu>System Preferences>Network). Click the Save button at the bottom of the screen to save the settings. Once you have the print server IP address set to fixed, you can then add the device as you would any printer via the Mac OS Printers & Scanners control panel. Go to Apple Menu>System Preferences>Printers & Scanners. Follow the instructions in the IOGear install instructions and enter the server’s fixed IP address in the “Address:” field as directed in the IOGear instructions. If you have a VPN router or modem, you may need to set port forwarding (port 631 and 9100 for this printer) to allow the printer’s data packets to travel across your network. If you have a router and don’t know what this means, get a techie to do so IF your printer doesn’t work after all other setup has been done.

The device works with hp laser jet pro cm 1415 fn color mfp?

I do not see that printer on their list of tested printers. https://www.iogear.com/files/pdf/GPSU21_PrinterCompatibilityList_201505.pdfThere is a 50/50 chance it might work just fine as long as your not using all the advanced features of the MFP.Use this unidirectional device is for sending a print job to print and that's it.

Will this work with an iPad?

Providing the ipad has an appropriate app as well as the drivers for your specific printer. The IOGEAR works great, you can set a static ip address. see the following link for some additional information: https://discussions.apple.com/message/18930908#18930908
