I would like it very much if I could check for the existence of a logical printer via proc.
Perhaps something like this....
if ($logicalprinter("HPLASER") = 1) ;-- where 1 exists and 0 does not
print "HPLASER","C"
endif

Hi.
You can do it using signatures.
Uniface stores logical printers info into windows registry.
You have to look if a key like this exists:
HKEY_CURRENT_USER\\Software\\Compuware\\Uniface\\USYS9\\PRT_PDF
where USYS9 is your Uniface installation directory and PRT_PDF is your printer name.
Look at ADVAPI32 (windows dll).

Hi,
Since 9.3 you can use the following to get a list of the PRT_xxx keys under the Uniface USYS9 registry key:
$1 = $setting("", "[PRT_<gold>*]", "REGKEYS")
This gets you a list of PRT_xxx values, representing all the local printer definitions you have made. You can use all the Uniface list functions to process this list. In case of error, $procerror is -1118 (non-existence of a key is not an error... that gets you an empty list!). Note that $setting is as yet undocumented and unsupported.
