If you are using SET PRINTER TO LPT1:, you shouldn't be having a problem. If you using SET PRINTER TO and using *ANY*
long name, the problem will eventually (and unpredictably) occur (also note that GETPRINTER() returns long names). I've also noticed that this problem did not appear to be in pre-SP3 VFP.

>>>Since service pack 3 of VFP6, my clients and I cannot print from NT. I get error 1958, error loading printer driver. We were all using HP drivers, and the problem dissappears for most after changing to MS drivers. However, it didn't help a few people. Can anyone successfully print from NT with an HP driver using VFP6 SP3? Anyone know why this would start occuring after installing SP3 runtimes? Thanks for any input, it is greatly appreciated.

>Thank you very much. Do you mean the actual name of the printer, or do you mean long file names in the path of the printer? I'm getting the error on machines printing to lpt1, but the printer names are definitely more than 8 characters: "HP Laserjet 6L" Is that what you're speaking of?
