use for hp photosmart printer .tell me if the printer is connected with icon in the tray .It is a usb connection .size 65,536 byte .tell me if there is a sd-card on the printer .
On one of my non-hp computers, I tried to scrub all HP Software from that system for a "fresh start" before reinstalling my HP 1600 Series Printer... Always HPZipm12 remained listed as running in the Task Manager list after startup. HP provides a security update for this PML Driver file to repair vulnerabilities. Avast, despite over 2000 false positive "reads" re this update, still sees it as a threat and puts it in the Virus Chest. I let the downloaded update go into the virus chest, then restored the HP PML Driver Update V1.0 Release 7 to the download folder (with exceptions w/r Avast). I then ran it, off line (Avast disabled). as admimistrator... There is now no loading of HPZipm12 at startup (as revealed in Windows XP Task Manager)... I feel safer now without the ancient legacy files loading relentlessly (even though it took a bit jockying to accomplish).

Loaded up with the sftware on an HP F300 scanner/printer, but wasn't uninstalled when I got rid of the printer. Its there everytime the computer starts up, but can be disabled thru Task Manager, and has no side effects.
Known to cause issues with Older XP systems running Older IBM and AMD processors. HP is still unable to resolve this issue. Recommend a full data back up and system restore (do not reinstall the printer) for anyone getting High CPU spikes after installing this driver.

I don't even have a printer, but for the past two days, this HPZip.exe has started running when I start up. It freezes my PC until I stop it. (Which isn't easy).
It and several others were installed when I installed an HP printer driver so I could use a hotel's printer with my laptop. I deinstalled the printer driver years ago but these 8 files remained: HPZidr12.dll, hpzids01.dll, HPZinw12.exe, HPZipm12.exe, HPZipr12.dll, HPZipt12.dll, HPZisn12.dll, hpzll4pi.dll. The two exe files were located in Program Files\HP\Digital Imaging--I had installed the driver in Program Files\HP--and the dll files were in WINDOWS\system32. I removed them all. All had the same internal Date Created of 5/16/2007 10:20 PM. When I presented them to my virus scanner, it found no problems. Conclusion: Cycle-stealing but harmless crap left behind by a bad HP deinstallation program. As I am not now using, nor have I ever purchased or used an HP imaging product, HP thus dishonestly installed unnecessary software.

Best practices for resolving HPZipm12 issues

A clean and tidy computer is the key requirement for avoiding problems with HPZipm12. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
