I am writing custom c++ data analysis scripts using gdb python api. If I have problem with my .py code I add print statements on every line to figure it out. Are better ways to debug pretty printers written in python?
I’ve got a color inkjet printer, and I only have black ink left.
I want my printer to automatically convert all colors printed to a grayscale equivalent.
I’d like a solution that works with any printer, not just my specific printer.
Is this possible using a virtual printer or something like that?
I have a new budget Kyocera network printer (FS-1061 DN). It has no wifi, but a standard LAN cable is plugged in. I installed the driver on my windows 7 machine, also connected via LAN, and printing works fine. From that (laptop) also printing via wifi works fine.
From my android smartphone (moto g 5+ with android 8.1) with both “kyocera printing plugin” and “kyocera mobile print” app, the printer is not detected.
- I checked wifi isolation in the router – ok.
- I used a network scanner app on the smartphone – it finds the device and shows various protocols that worked: most notably SNMP v2 and v3.
- I entered the IP manually. – “Cant connect to printer”.
- I tried both protocols: WS Discovery and SNMP
But still the printer is not detected from the printing apps.
Any tips? Perhaps a setting on the smartphone?
LAN printer installed. Unable to print because of auth, and not see where to enter login password.
Printer installed on neighbor lan(nested router), routing and firewalls configured. Its on Ubuntu 18.04.1, same as where I try to print from. How to make it guest-accessible, or what to do with auth? Its found as ipp://192.168.2.51:631/ipp , may be samba sharing will be easier? In printer properties there are no login/password options.
I have someone with a computer that they do not have access to admin privileges in, states away from me so can’t go fix it in person and don’t want to give them the admin password, trying to install printer drivers on their computer. I tried taking control of their desktop and right click install as admin thinking it would prompt me for admin login but it didn’t and it went right through the install process then stopped at the end telling me user did not have privileges. The network isn’t set up where he is so I can’t connect in that way and there is a firewall up preventing remoting through windows remote desktop connection. Any potential ideas on how to fix would be appreciated, just need to get some printer drivers installed.
I am very new to “networking” and security, but I realize that it would be more secure to have printers on their own “isolated network”.
- How do I secure my networked printers?
- What kind of printers do the most secure companies use?
I am unsure what the correct or what a good structure is for creating an “isolated network”. Wondering if it means essentially this (for a home-based system):
- Create a second account with some ISP, or perhaps just ask for some separate thingy on the existing account.
- Buy a second router.
- Disable internet access for this router, so it only functions as a local wifi system. Or maybe the printers don’t need wifi and can use ethernet instead.
- Connect a laptop to the network somehow, so it can send its print jobs to the printer.
I can see a few holes in that so far, and it seems incomplete. I’m wondering what the typical system is for making a secure isolated network such as for these printers, which you can still send commands to only from specific places (like from a laptop or phone).
So USB is inherently insecure. I’m wondering if you could simply attach a USB to firewire adapter to the USB chord of a printer to connect the printer to a Mac for use.
Assuming the printer is not attached to the network or router or anything, I’m wondering if connecting the USB to the computer will pose any security risks. That post suggests that just by plugging a USB stick into your computer it could run native code and install malware. I’m on a Mac, I don’t know if this is technically possible in the case of the connection being a USB chord with a wifi-enabled, yet network disconnected printer on the other end.
I am look at this which basically says you can simply configure your printer from the printer LCD screen by entering the wifi password and boom you’re done. This means you don’t have to install any drivers which I would like to avoid. However, I’m not sure about the security of giving the printer your wifi password, so I wanted to see if there’s a way to install a printer on a Mac using a USB cable, which doesn’t require using a software driver/installation. That is, I would imagine there is some printer where you simply plug it into your Mac and it shows up in some settings panel and you can simply open a PDF in Preview and press “Print to X printer”, and you would get all of this without having to install drivers or connect through wifi. Or if this is not possible I’d be interested to know why. I’d also be interested to know if connecting to USB is a security risk, but that’s a separate question 🙂
I am looking at these instructions which suggest basically giving the wireless printer your network password to configure it. I don’t know enough about security or networks to know the implications of it and wanted to know if there are any potential security risks in doing this. It seems more secure to give it the network password so it can use the network, rather than directly connecting it via ethernet to the router. I don’t think just by giving it the network password it could do anything, but perhaps it opens up the possibility of broadcasting that network password to a centralized place on the internet, which allows others to connect into the network remotely haha. I don’t know, just trying to learn more about security with each new device I’m exploring. This and its links to other articles was helpful.
