Narrative:
During leveloff at approximately 8000 ft, controller queried our altitude and pointed out traffic. Controller queried altitude again and asked for our last altimeter setting. Altimeters were set to 30.00. Actual altimeter was 30.32. Corrected aircraft altimeter resulting in large altitude correction. The only altimeter setting received to that point was from the ACARS ATIS printout. Printout was smudged due to dirty print head or defective paper. Appeared to read 30.00 rather than actual value. Parking area was old without actual elevation posted, neither crew member had been to this airport before, deice was in progress and somehow the discrepancy was not noted during the checklists. Would suggest that when ACARS and pre departure clearance are in use that at least one time prior to takeoff, ground control or tower issue an altimeter setting for readback.

Title: EMB135 FLC UNDERSHOT INTERMEDIATE DEP ALT DUE TO WRONG ALTIMETER SETTING.
Narrative: DURING LEVELOFF AT APPROX 8000 FT, CTLR QUERIED OUR ALT AND POINTED OUT TFC. CTLR QUERIED ALT AGAIN AND ASKED FOR OUR LAST ALTIMETER SETTING. ALTIMETERS WERE SET TO 30.00. ACTUAL ALTIMETER WAS 30.32. CORRECTED ACFT ALTIMETER RESULTING IN LARGE ALT CORRECTION. THE ONLY ALTIMETER SETTING RECEIVED TO THAT POINT WAS FROM THE ACARS ATIS PRINTOUT. PRINTOUT WAS SMUDGED DUE TO DIRTY PRINT HEAD OR DEFECTIVE PAPER. APPEARED TO READ 30.00 RATHER THAN ACTUAL VALUE. PARKING AREA WAS OLD WITHOUT ACTUAL ELEVATION POSTED, NEITHER CREW MEMBER HAD BEEN TO THIS ARPT BEFORE, DEICE WAS IN PROGRESS AND SOMEHOW THE DISCREPANCY WAS NOT NOTED DURING THE CHKLISTS. WOULD SUGGEST THAT WHEN ACARS AND PDC ARE IN USE THAT AT LEAST ONE TIME PRIOR TO TKOF, GND CTL OR TWR ISSUE AN ALTIMETER SETTING FOR READBACK.
