Printer Connected but Not Printing, Not Accepting Print Jobs, and Cartridge Errors

A printer can look completely normal from the outside and still refuse to produce a single page. In these situations, the device may appear in Windows, respond to pings, show up in the manufacturer’s app, or even handle scanning correctly while print jobs go nowhere. That is what makes this kind of failure so misleading. The printer does not look disconnected, and the system often gives just enough feedback to suggest that communication is working.

What follows are situations where the printer was clearly present in the environment but still would not print. Sometimes the problem sat in the connection path between the system and the device. In other cases, the printer accepted jobs but never processed them, or only failed from one computer while continuing to work everywhere else. 

These examples focus on what actually changed the outcome when the printer was visible, reachable, or apparently ready, yet still did not print.

Problem: Printer is connected to Wi-Fi but cannot print from Windows

What users observed: The printer showed as connected to Wi-Fi and appeared configured normally, yet computers could not send successful print jobs to it. In one Epson WorkForce Pro WF-C579R case, USB printing still worked, which made the wireless failure even harder to interpret. The printer looked online, had the expected IP range, and did not behave like a dead device.

What was tried: Reinstalling software, resetting the printer, and repeating setup did not restore wireless printing. The connection looked valid from the printer side, but devices on the network still could not communicate with it properly.

How this played out: Printing only began working after router settings were changed. Before that, the printer remained connected but unreachable, which meant the issue was not that the device had failed to join Wi-Fi. The problem was that being “connected” did not translate into usable communication.

Problem: Printer is visible but cannot print (Linux)

What users observed: After switching to Linux Mint 22.1, the Samsung M2070 appeared present and selectable, but print jobs stalled without any physical output. The paper tray and queue could still show activity, which made it look as though printing was about to start, but nothing actually printed.

What was tried: Multiple attempts focused on configuration while leaving the same software stack in place. The printer continued to appear available, so the setup did not look obviously broken.

How this played out: Printing only began once the driver source was changed to match the current support path for the printer line. Earlier attempts did not produce partial improvement. The problem was not that the printer was missing; it was present, but the environment handling the print path was not compatible with how the device now needed to be supported.

Problem: Printer is reachable by IP but not printing

What users observed: On several HP LaserJet M402n units, printers remained reachable by IP address and their web interfaces loaded normally, yet print jobs failed. From the network side, the printers looked online and alive. From the user side, they simply stopped producing output.

What was tried: Temporary fixes included rebooting printers, rebooting the print server, and changing ports assigned to the queues. The printers were not disappearing from the network, so the issue did not behave like a normal connectivity failure.

How this played out: Printing stabilized when queues were moved away from WSD ports and onto standard TCP/IP ports. The printers had been connected the whole time. What changed was the path the jobs used to reach them.

Problem: Printer scans successfully, but printing still does not work

What users observed: On the HP LaserJet MFP M234sdw, scanning continued to work and the printer reported a live Wi-Fi connection, but HP Smart still showed it as offline and neither Windows nor an iPad could print to it. This kind of split behavior made the failure especially confusing, because one part of the device was clearly functioning.

What was tried: Users followed multiple HP troubleshooting steps and also disabled Smart Install, expecting that a software path or local configuration issue might be blocking printing.

How this played out: No confirmed fix was documented. The printer remained able to scan while refusing to print, which left it in a partially functional but unreliable state.

Problem: Printer works from other computers but not from one specific system

What users observed: A Canon iPF785 worked normally for multiple Windows 11 machines, but one specific Windows 11 computer suddenly could not print. The printer and host system disappeared from that machine’s list, then later reappeared, but printing still failed from that one computer while continuing to work elsewhere.

What was tried: Remote troubleshooting continued over several days. Visibility came and went, but the ability to actually print did not return.

How this played out: No confirmed resolution was documented. Because the printer remained functional from other computers, the problem stayed isolated to that one environment rather than to the device itself.

Problem: Printer accepts jobs but remains stuck on “Receiving Data” or “Printing”

What users observed: On the Brother HL-L5200DW, the display could remain frozen on “Receiving Data” or “Printing,” even though no pages were produced and no jobs completed. In some cases, one document would print and the next would stall, leaving the printer apparently active but not progressing.

What was tried: Hard power-off, cable disconnection, restart in isolation, firmware updates, and reinstall attempts were all used to try to clear the state.

How this played out: In some cases, restarting cleared the condition temporarily. In others, the state returned and no consistent fix was identified. The printer was not disconnected; it was simply not moving past the point where it had begun receiving the job.

Problem: Printer is installed and set as default, but reports jobs as finished without printing

What users observed: On the HP LaserJet P1006, the printer could appear installed and set as default, while test pages and documents reported successful completion without any paper output. The same physical printer worked from another system, which made the failure look local rather than mechanical.

What was tried: Reinstallation and setup tools were used again, but the behavior did not change while the affected system remained in the same state.

How this played out: A later operating system update restored printing without changing the printer setup itself. The printer had not been disconnected, and the job system still thought printing was succeeding. The breakdown happened somewhere between job completion and actual output.

Problem: Printer is connected, but pauses or blocks its own jobs because of paper configuration

What users observed: On the HP LaserJet M402n, jobs could begin normally but then stop between pages, repeatedly ask for Tray 1, or behave as though the printer was waiting for manual input. To the user, it looked like the printer had frozen or stopped printing for no reason.

What was tried: Print job settings were reviewed, especially media type and size. The hardware was not failing in a general way, because the printer still responded and could continue once the prompt was satisfied.

How this played out: The slow, stop-start behavior ended when the job settings matched the actual tray configuration. The printer had been connected and responsive throughout, but the job itself was forcing it into a state that prevented continuous printing.

Problem: Printer is connected but refuses to print

What users observed: A second-hand HP LaserJet MFP M234sdw remained in an orange error-light state and refused to print even after resets, firmware checks, and normal setup attempts. The device was present and powered, but effectively unusable.

What was tried: Power cycling, cleaning, resets, and firmware verification did not restore printing.

How this played out: Replacing the toner cartridge cleared the condition completely. The printer had not been suffering from a normal connection failure. It was connected, but blocked by an internal state that prevented jobs from going through.
