Printing Problems

If there is no printing in Windows (or Windows 95) but TOVA prints fine..... or

Windows 95 does not start properly with TOVA hardware attached but fine without...

It usually occurs with Hewlett Packard printers or printers looking for specific hardware but may occur with other printers. The problem usually is that the computer is looking for specific type of signals (Hewlett Packard signals) and non-HP devices (like TOVA) interfere or are not recognized by the Windows environment.

The simplest solution is to use more Generic drivers when installing or setting up the printer. If you use more generic or compatible drivers from within Windows or the drivers already installed on the Windows system, they tend to allow for more generic devices (like TOVA's hardware or other parallel devices). The printer's manual may list several compatible printers types to emulate that will work with your printer. For example, using the HP III from Windows usually works with most HP printers. If the listing in Windows lists you exact printer and you don't use the install disks that came with your printer, then that printer should work as well. None the less, using different more generic drivers for the printer usually solves most TOVA hardware interference.

There can also be certain settings in the properties of the printer or parallel port which keep non-printing parallel devices (like TOVA) from working. Some of the settings can be: Disabling or turning off "BI-directional communications" and havi ng only uni-directional printing or parallel card; Turning off or disabling of "Print Cartridge query"; Turning off "Fast printing direct to port" can also help.

Sometimes there is interfering software loading (like Networks and other drivers) that keep the hardware from being seen or working properly. The simplest way to see if software is interfering with the hardware (printing or TOVA) is to not load or bypass the startup files of the computer.

With MS-DOS based machines running DOS 6 or higher...

When you turn on or boot up the computer, it should say in text, "Starting MS Dos...", at some point in the very beginning of the startup. When that "Stt, "Starting MS Dos...", at some point in the very beginning of the startup. When that "Starting MS DOS..." prompt is seen press the F5 key to bypass the start up files (AUTOEXEC.BAT & CONFIG .SYS). It should bring you to a C:> prompt. Run TOVA and try everything out from there.

With Windows 95 machines...

When you turn on or boot up the computer, it should say in text, "Starting MS Dos...", at some point in the very beginning of the startup. When that "Starting MS DOS..." prompt is seen press the F8 to go to the Optional Startup Menu. From the Option al Start Up Menu list you can select either COMMAND PROMPT ONLY or SAFE MODE COMMAND PROMPT ONLY either options will bypass some files that may interfere. After selecting either of those options it should bring you to a plain C:> prompt, from the re you can type TOVA to start the TOVA program (if it's been installed) and try everything out from there.
