Dear cbdobbin
Sorry for the delay in responding - I was having trouble getting the Forum to come up. It seems to be working now.
It sounds like your Dealer will be coming to your office to help you with this, as nothing seems to be working.
One thing does come to mind - what emulation do you have selected for this printer driver? The HP one, or "PCL..." If you are using the PCLxx driver, change it and use the HP emulation instead. We have heard of problems with certain versions of the PCL emulation, but in all other cases they have given an error with "PCLxx..." in the description so it has been easy to identify.
If you have indeed tried all my other suggestions (including re-installing Checks), then I do not know what else to suggest as your problems started only after you changed printers and installed the new printer driver.
I hope your Dealer will be able to get it resolved. Please let us know!
Sincerely,
Softrak Support
