To change speed and darkness of Zebra Eltron LP 2844 (2543/2442 is similar)

(for Zebra driver only -- UPS driver is similar):

SPECIAL NOTICE:
- Typical market price for BRAND NEW Zebra LP2844 thermal printers may be sold around $500 - $1000, by leasing companies (such as 3-year contract with $30/month leasing fee).
- Finding an optimal speed/darkness setting is very important for thermal printers, this is especially true for not-brand-new thermal printers.
- Parallel connection usually is easier to set up than USB connections, due to Windows may assign new USB Port # to a device every time you disconnect and re-connect a usb device. For USB connection, under certain circumstances, you might have to adjust USB port # manually, or re-boot Windows, re-do "Add a new printer" in Control Panel.
- Use UPS.com's driver for ups programs, use zebra.com's driver for other programs.
- SELF-TEST: Turn power switch in back to off, hold green button, turn power on. Till green button becomes flashing red, release green button. Wait till printer spits 3 empty page, and 1 page of diagnostic results, hit green button once more. Print will spit another page, with "Out of Dump" on it, that ends the self-test mode, return to normal page mode.
- Too old thermal label paper may NOT generate good printing results, please try with your fresh (recently-ordered) labels first.
Go to "Control Panel", right click your "Zebra LP 2844", go to "Properties":
Go to "Printing Preferences"
Go to "Document", "Device Options", "Speed Settings", "Head Settings"
Try to adjust speed to lowest, darkness to darkest, see whether you can get better results.

For UPS drivers, you need follow "Properties" --> "Printing Preferences" --> "Advanced" .

All of our tests are performed on Windows 2000 and XP. Zebra.com has updated driver for Windows Vista -- but we haven't tried yet. And we don't know whether it works for Mac OS or not (zebra doesn't provide driver for Mac OS either).

Sometimes under XP, it is necessory to adjust USB port manually (XP may automatically generate/assign new USB port for the printer upon reboot/re-connection, under some circumstances):
